    <dcterms:abstract><![CDATA[<p><strong>RESUMEN<br /> Introducci&oacute;n: </strong>Las met&aacute;stasis de cr&aacute;neo son raras, los m&aacute;s frecuentes son carcinoma de pulm&oacute;n, mama y pr&oacute;stata. Las de origen tiroideo son extremadamente raras, la mayor&iacute;a atribuida al subtipo folicular. El diagn&oacute;stico diferencial de tales lesiones, es esencial para el tratamiento y evoluci&oacute;n. Describimos un caso de met&aacute;stasis de calota por carcinoma folicular de tiroides.<br /> <strong>Material y m&eacute;todos:</strong> Paciente femenina, 60 a&ntilde;os de edad, sin APP conocidos. Consulto por masa subd&eacute;rmica a nivel occipital izquierda, firme, adherida a planos profundas de crecimiento gradual, de 3 a&ntilde;os de evoluci&oacute;n, asintom&aacute;tica. TAC e IRM: lesi&oacute;n expansiva intracraneal epidural y extracraneal osteol&iacute;tica a nivel parieto-occipital izquierdo de 34x68x52 mm. Angiograf&iacute;a cerebral: aferente principal arteria occipital posterior izquierda y drenaje venoso a seno longitudinal sin compromiso del mismo. Se realiza exeresis quir&uacute;rgica de lesi&oacute;n l&iacute;tica &oacute;sea extradural sin compromiso dural, macrosc&oacute;picamente completa y posterior craneoplast&iacute;a. Histol&oacute;gia: carcinoma folicular de tiroides.<br /> <strong>Resultados:</strong> La incidencia de carcinoma de tiroides representa aproximadamente el 1% de todos los tumores. El subtipo folicular, es el segundo en frecuencia (10-15%). La met&aacute;stasis craneal representa el 2,5% aproximadamente, siendo m&aacute;s frecuente en la regi&oacute;n occipital, seg&uacute;n la serie publicada por Nagamine et al. La edad media de presentaci&oacute;n fue de 60 a&ntilde;os y con preponderancia femenina. La propagaci&oacute;n del mismo es probablemente por v&iacute;a hemat&oacute;gena. Estos pueden tener una cl&iacute;nica silente. En las im&aacute;genes, se manifiestan como lesiones osteol&iacute;ticas altamente vascularizadas. En nuestro caso, se obtuvo el diagn&oacute;stico definitivo a trav&eacute;s de la anatom&iacute;a patol&oacute;gica, debido a que tanto las im&aacute;genes y la cl&iacute;nica, no nos suger&iacute;an secundarismo.<br /> <strong>Conclusi&oacute;n: </strong>A pesar de la poca frecuencia de esta patolog&iacute;a, no debe de ser subestimada a la hora de la extirpaci&oacute;n de este tipo de lesiones.</p>

    <dcterms:abstract><![CDATA[<strong>RESUMEN<br /> Introducci&oacute;n</strong>: El abordaje endonasal endosc&oacute;pico permite un acceso a la base del cr&aacute;neo a trav&eacute;s de una cavidad natural. Mediante &eacute;l, es posible acceder a patolog&iacute;as que afectan tanto a las fosas anterior, media y posterior. A su vez, el &iacute;ndice de complicaciones postoperatorias es menor en comparaci&oacute;n con el abordaje endonasal microquir&uacute;rgico cl&aacute;sico.<br /> <strong>Objetivo:</strong> Describir exhaustivamente las diferentes fases del abordaje endonasal endosc&oacute;pico, resaltando sus principales reparos anat&oacute;micos, poniendo especial &eacute;nfasis en sus alcances a la amplia gama de patolog&iacute;as de la base del cr&aacute;neo. Se propone analizar la manera en la que fue aplicado dicho acceso en nuestra experiencia quir&uacute;rgica.<br /> <strong>Materiales y m&eacute;todos:</strong> Se realiza una descripci&oacute;n detallada de la anatom&iacute;a endosc&oacute;pica particular de cada fase del acceso endonasal a la base del cr&aacute;neo, echando luz sobre los principales reparos anat&oacute;micos se confeccion&oacute; finalmente un an&aacute;lisis retrospectivo en nuestra serie quir&uacute;rgica de 51 pacientes intervenidos v&iacute;a endosc&oacute;pica endonasal durante el lapso 2012 y marzo de 2015, evaluando los resultados de dichas intervenciones, la tasa de complicaciones y los controles por im.genes postoperatorios.<br /> <strong>Resultados:</strong> El abordaje endosc&oacute;pico a la base del cr&aacute;neo fue pasible de una detallada caracterizaci&oacute;n anat&oacute;mica. Mediante &eacute;l pudieron resolverse afecciones de la fosa craneal anterior (rabdomiosarcomas y meningiomas), media (de la regi&oacute;n selar y paraselar) y posterior (cordomas del clivus).<br /> Conclusi&oacute;n: El abordaje endonasal endosc&oacute;pico a la base del cr&aacute;neo no es tan solo complejo por sus numerosas fases sino tambi&eacute;n por los incontables reparos anat&oacute;micos que caracterizan a cada una de ellas. Dicho abordaje provee un acceso a la base del cr&aacute;neo mediante una cavidad anat&oacute;mica con una baja incidencia de complicaciones.

    <dcterms:abstract><![CDATA[<strong>RESUMEN<br /> Introducci&oacute;n: </strong>Los hemangioblastomas (HEB) son tumores poco frecuentes del sistema nervioso central (SNC) representando el 1-2,5% de todos los tumores intracraneanos. Pueden presentarse espor&aacute;dicamente o en el contexto del s&iacute;ndrome de von Hippel-Lindau (VHL), predominando en el cerebelo, tronco cerebral y m&eacute;dula espinal. El s&iacute;ndrome de VHL es un s&iacute;ndrome neopl&aacute;sico m&uacute;ltiple transmitido en forma autos&oacute;mica dominante causado por la deleci&oacute;n del gen supresor del VHL. Presentamos nuestra experiencia en el tratamiento de los pacientes con HEB.<br /> <strong>Material y m&eacute;todo:</strong> Cuarenta pacientes consecutivos con HEB fueron incluidos en este estudio. Las historias cl&iacute;nicas, im&aacute;genes radiol&oacute;gicas y partes quir&uacute;rgicos fueron analizados. Se utiliz&oacute; la escala modificada de Rankin para evaluar el curso cl&iacute;nico de las lesiones intracraneanas y la escala de Mc Cormick para las medulares.<br /> <strong>Resultados: </strong>Treinta HEB (75%) se localizaron en el cerebelo, 6 (15%) en el tronco cerebral, 2 (5%) en la m&eacute;dula espinal y 1 (2,5%) en regi&oacute;n supratentorial y cauda equina respectivamente. Treinta y cinco (87,5%) lesiones fueron espor&aacute;dicas y 5 (12,5%) se dieron en el contexto de VHL. Resecci&oacute;n completa se obtuvo en 93% de las lesiones cerebelosas y en el 83% de las de tronco cerebral. Postoperatoriamente, 83% de los HEB cerebelosos y 66,6% de los de tronco cerebral mostraron buenos resultados funcionales.<br /> <strong>Conclusiones: </strong>Los HEB del SNC deben ser resecados cuando presentan s&iacute;ntomas o evidencias de crecimiento radiol&oacute;gico. La resecci&oacute;n deber&iacute;a ser en bloque para disminuir el sangrado intraoperatorio. Los pacientes con HEB deben ser evaluados para descartar el s&iacute;ndrome de VHL y en casos confirmados la familia deber&iacute;a realizar la consulta gen&eacute;tica.

    <dcterms:abstract><![CDATA[<strong>RESUMEN<br /> Objetivo:</strong> Describir paso a paso el abordaje a la cisterna ambiens por la vía suboccipital retrosigmoidea supracerebelosa infratentorial (SRSI).<br /> <strong>Descripción: </strong>El abordaje SRSI se realiza de la misma manera que el abordaje suboccipital retrosigmoideo (SR), utilizado habitualmente para acceder a la patología del ángulo pontocerebeloso, con las siguientes modificaciones: 1) utilizamos siempre la posición semisentado, 2) la craneotomia-craniectomia debe exponer el seno transverso y extenderse 5 cm medialmente hacia el inion, 3) al realizar la apertura dural es necesario rebatir la duramadre junto con el seno transverso hacia cefálico con puntos de tracción, 4) bajo magnificación con microscopio quirúrgico se debe realizar la apertura de la cisterna cerebelobulbar para drenar líquido cefalorraquídeo, 5) en el plano supracerebeloso es fundamental cortar las bridas aracnoidales y de ser necesario debemos coagular y cortar las venas puente, todas estas maniobras sumadas al efecto de la gravedad brindan mayor apertura del corredor supracerebeloso.<br /> <strong>Conclusión:</strong> El abordaje a la cisterna ambiens por la vía SRSI es una opción segura para el acceso de patologías tumorales que se alojan en esta zona con un componente predominantemente infratentorial.

    <dcterms:abstract><![CDATA[<strong>RESUMEN</strong><br /> <strong>Objetivo:</strong> Determinar el patr&oacute;n de expansi&oacute;n de los adenomas hipofisarios (AH), as&iacute; como la variaci&oacute;n del patr&oacute;n de crecimiento entre tumores no funcionantes, prolactinomas, y tumores productores de hormona de crecimiento.<br /> <strong>Pacientes y M&eacute;todo:</strong> Se estudiaron los AH (no funcionantes, prolactinomas, y productores de hormona de crecimiento), operados entre julio de 2005 y diciembre de 2012, que presentaban una extensi&oacute;n m&aacute;s all&aacute; de los l&iacute;mites de la fosa hipofisaria. Para el an&aacute;lisis de asociaci&oacute;n se calcul&oacute; el Test Chi Cuadrado. <br /> <strong>Resultados: </strong>91 casos cumplieron con los criterios de inclusi&oacute;n. Cuarenta y nueve presentaron tumores no funcionantes, 22 prolactinomas y 20 acromegalias. El patr&oacute;n de crecimiento global de los AH fue: 85% hacia la regi&oacute;n supraselar, 57% hacia el seno esfenoidal, y 27% hacia el seno cavernoso. El 96% de los pacientes con adenomas no funcionantes presentaron una extensi&oacute;n supraselar, y el 80% de los pacientes con acromegalia mostraron una extensi&oacute;n hacia el seno esfenoidal.<br /> <strong>Conclusi&oacute;n: </strong>El patr&oacute;n de crecimiento de los AH se asocia al tipo de tumor; el crecimiento supraselar es m&aacute;s frecuente en los tumores no funcionantes, mientras que el crecimiento hacia el seno esfenoidal es m&aacute;s frecuente en los pacientes con acromegalia.

    <dcterms:abstract><![CDATA[<strong>RESUMEN</strong><br /> <strong>Objetivo:</strong> La acromegalia es un desorden poco frecuente causado por la hipersecreci&oacute;n anormal de hormona de crecimiento por parte de un adenoma hipofisario. La cirug&iacute;a transesfenoidal es generalmente la primera opci&oacute;n terap&eacute;utica. <br /> El objetivo de este art&iacute;culo es establecer la efectividad del abordaje trasnasal-transesfenoidal en el tratamiento de los adenomas productores de GH e identificar factores de riesgo de persistencia de la enfermedad. <br /> <strong>Material y M&eacute;todos: S</strong>e realiz&oacute; una revisi&oacute;n retrospectiva de 81 pacientes tratados de acromegalia con cirug&iacute;a transesfenoidal entre los a&ntilde;os 2006 y 2010. <br /> <strong>Resultados: </strong>Los adenomas mayores a 1 cm (macroadenomas) representaron el 66.7% de los casos. En el 28.4% de estos pacientes (n=23) se evidenci&oacute; en la RMN de cerebro con gadolinio invasi&oacute;n del seno cavernoso. La curaci&oacute;n de la enfermedad, tanto oncol&oacute;gica como hormonal, se alcanz&oacute; en el 72.8% (n=59). Todos los microadenomas (n=27) fueron manejados efectivamente con cirug&iacute;a transnasal-transesfenoidal, mientras que la curaci&oacute;n completa en el caso de los macroadenomas fue del 66.7%. El an&aacute;lisis estad&iacute;stico univariado demostr&oacute; que la persistencia de la enfermedad se encontraba estad&iacute;sticamente asociada con tres variables: tama&ntilde;o tumoral, valores hormonales preoperatorios e invasi&oacute;n del seno cavernoso. El odds ratio para la remisi&oacute;n completa de la enfermedad fue de 1.68 para los microadenomas y de 0.033 para los macroadenomas con invasi&oacute;n del seno cavernoso (p&lt;0.001). Los valores de GH preoperatorios se relacionaron estad&iacute;sticamente con curaci&oacute;n de la enfermedad durante el per&iacute;odo de seguimiento (p&lt;0.05). Sin embargo tras realizar un an&aacute;lisis de regresi&oacute;n log&iacute;stica multivariado se demostr&oacute; que la invasi&oacute;n del seno cavernoso es la &uacute;nica variante que se asocia significativamente con la persistencia de la enfermedad (OR 3.52, p&lt;0.05). <br /> <strong>Conclusi&oacute;n:</strong> El abordaje transnasal resulta ser efectivo en el tratamiento y curaci&oacute;n de la acromegalia. La invasi&oacute;n del seno cavernoso es el mejor predictor de persistencia de la enfermedad.

    <dcterms:abstract><![CDATA[<p><strong>RESUMEN<br /> Objetivo:</strong> Reportar un caso de mixoma yuxtaarticular lumbar y revisi&oacute;n de la literatura. <br /> <strong>Descripci&oacute;n: </strong>Paciente de sexo femenino, de 50 a&ntilde;os, sin antecedentes m&eacute;dicos de inter&eacute;s, consult&oacute; por lumbalgia cr&oacute;nica. La exploraci&oacute;n neurol&oacute;gica s&oacute;lo constat&oacute; una debilidad por impotencia funcional en miembro inferior derecho. La RMN de columna lumbo-sacra evidenci&oacute; una lesi&oacute;n expansiva a nivel de L4, en el espesor de la musculatura paravertebral, de aspecto qu&iacute;stico. <br /> <strong>Intervenci&oacute;n: </strong>Se realiz&oacute; una cirug&iacute;a de ex&eacute;resis de la lesi&oacute;n tumoral, mediante abordaje posterior miniinvasivo y asistencia videoendosc&oacute;pica, logrando una resecci&oacute;n macrosc&oacute;pica total. El estudio an&aacute;tomo-patol&oacute;gico dilucid&oacute; que se trataba de un mixoma. La inmuno-fenotipificaci&oacute;n fue positiva para vimentina. En el posoperatorio present&oacute; un hematoma de herida quir&uacute;rgica, que resolvi&oacute; espont&aacute;neamente. La evoluci&oacute;n ulterior fue favorable, con remisi&oacute;n del cuadro doloroso. Se efectuaron controles de resonancia magn&eacute;tica posoperatorios, a los tres meses y a los dos a&ntilde;os; no se constat&oacute; recidiva de la lesi&oacute;n tumoral. Actualmente la paciente cursa treinta meses de posoperatorio y se encuentra asintom&aacute;tica. <br /> <strong>Conclusi&oacute;n:</strong> La localizaci&oacute;n lumbar paravertebral es excepcional en el mixoma yuxta-articular. La resecci&oacute;n quir&uacute;rgica total es el tratamiento de elecci&oacute;n, ya que suele ser curativa.</p>]]></dcterms:abstract>

    <dcterms:abstract><![CDATA[<p><strong>RESUMEN</strong><br /> <strong>Objetivo</strong>: El propósito del presente trabajo es presentar los resultados de 13 pacientes con diagnóstico de espasmo hemifacial (EHF), en los cuales se realizó una descompresión microvascular (DMV).<br /> <strong>Material y Método:</strong> Desde Junio de 2005 a Mayo de 2014, 13 pacientes con diagnóstico de EHF fueron intervenidos quirúrgicamente, realizando una DMV. Se evaluó: edad, sexo, tiempo de evolución de la sintomatología, hallazgos<br /> intraoperatorios y resultados postoperatorios.<br /> <strong>Resultados: </strong>De los 13 pacientes intervenidos, 7 fueron mujeres y 6 varones. La media de edad fue de 53 años. El tiempo medio entre el inicio de la sintomatología y la intervención quirúrgica osciló entre 3 y 9 años. En todos los casos el EHF era típico, uno de ellos con neuralgia trigeminal concomitante, observándose en todos compresión neurovascular intraoperatoria. Por orden decreciente de frecuencia la causa de la compresión fue arteria cerebelosa anteroinferior, arteria cerebelosa posteroinferior, arteria dolicomega basilar y arteria dolicomega vertebral. El seguimiento postoperatorio fue en promedio de 24 meses. El 62% presentó desaparición postquirúrgica inmediata de la sintomatología preoperatoria, el 30% desaparición tras un período de 3 semanas a 2 meses (8% con mejoría parcial), y en el 8% no hubo mejoría. En cuanto a las complicaciones postoperatorias: 3 pacientes presentaron paresia facial II-III en la escala de House-Brackman (se recuperaron en un período de 6 meses), y 1 paciente presentó fístula de líquido cefalorraquídeo. Ninguno de los pacientes de la serie presentaron hipoacusia transitorio o permanente.<br /> <strong>Conclusión: </strong>La DMV como tratamiento del EHF es un procedimiento efectivo y seguro, que permite la resolución completa de la patología en la mayoría de los casos.</p>

    <dcterms:abstract><![CDATA[<p><strong>RESUMEN<br /> Introducci&oacute;n:</strong> Se define como craneoplastia a la reparaci&oacute;n quir&uacute;rgica de los defectos &oacute;seos craneanos. En nuestro medio el material utilizado mayormente es el hueso aut&oacute;logo criopreservado (HACp) y, en caso de no contar con dicho tejido, el Polimetilmetacrilato (PMMA) es de elecci&oacute;n. <br /> <strong>Objetivo:</strong> Se plantea un estudio retrospectivo observacional a fin de analizar y comparar complicaciones en pacientes sometidos a craneoplastias con HACp en comparaci&oacute;n a un grupo de pacientes a los que se les realiz&oacute; craneoplastia con PMMA.<br /> <strong>Materiales y m&eacute;todos: </strong>Se incluyeron pacientes que fueron sometidos a craneopat&iacute;as durante un periodo de 5 a&ntilde;os (2008-2013). El seguimiento delos pacientes fue de al menos 12 meses. Se analizaron variables relacionadas a complicaciones tempranas y tard&iacute;as.<br /> <strong>Resultados:</strong> 63 pacientes recibieron craneoplastia con HACp (31 pacientes, 52%) o polimetilmetacrilato (31 pacientes, 49%). La tasa de complicaci&oacute;n global fue del 36,6%. Doce pacientes (19,04%) requirieron tratamiento quir&uacute;rgico. Las complicaciones m&aacute;s frecuentes fueron las colecciones subcut&aacute;neas no infectadas (19%), seguidas por las infecciones de heridas (17%). No existen diferencias estad&iacute;sticamente significativas en cuanto a para complicaciones, tanto globales como en las distintas categor&iacute;as (p&gt;0,05), para ambas t&eacute;cnicas quir&uacute;rgicas. <br /> <strong>Conclusi&oacute;n: </strong>Las craneoplastias tanto con HACp como aquellas con PMMA presentan una alta tasa de complicaciones. En nuestra serie no se hallaron diferencias entre ambos grupos estudiados.</p>

    <dcterms:abstract><![CDATA[<p><strong>RESUMEN</strong><br /> <strong>Introducci&oacute;n:</strong> El s&iacute;ndrome de Hakim Adams, o hidrocefalia normotensiva, es un cuadro progresivo que se caracteriza por presentar alteraci&oacute;n de la marcha, trastornos esfinterianos y demencia, y que afecta principalmente a pacientes a&ntilde;osos. Si bien existen publicaciones sobre los resultados del tratamiento quir&uacute;rgico, estos trabajos suelen evaluar la mejor&iacute;a sintom&aacute;tica pero no la calidad de vida de los pacientes. <br /> <strong>Objetivo: </strong>Conocer el impacto del tratamiento en pacientes con s&iacute;ndrome de Hakim Adams tratados con derivaci&oacute;n de LCR. <br /> <strong>Material y M&eacute;todos:</strong> Realizamos un estudio retrospectivo de una serie de 8 pacientes. Se realiz&oacute; una encuesta para la evaluaci&oacute;n preoperatoria y postoperatoria; con un tiempo transcurrido no menor a 6 meses luego del procedimiento. Se utiliz&oacute; la escala de Barthel para la funcionalidad, y una escala num&eacute;rica simple para la calidad de vida. <br /> Resultados: Previo a la cirug&iacute;a, 7 casos presentaban alteraciones de la marcha y/o problemas para deambular; 6 casos alteraciones esfinterianas; y 5 casos alg&uacute;n tipo de alteraci&oacute;n neurocognitiva. Luego de la cirug&iacute;a, todos los pacientes refirieron un cambio significativo en la calidad de vida; y tambi&eacute;n en la funcionalidad, logrando 6 pacientes una independencia absoluta. <br /> <strong>Conclusi&oacute;n: </strong>Aunque nuestra comunicaci&oacute;n tiene las debilidades de una serie peque&ntilde;a de casos analizados en forma retrospectiva, los resultados son concluyentes en cuanto a mejora en la calidad de vida y funcionalidad en el postoperatorio. Creemos que esta modalidad de evaluaci&oacute;n puede ayudar a los pacientes y/o familiares de pacientes en el proceso de toma decisiones del tratamiento quir&uacute;rgico.</p>

    <dcterms:abstract><![CDATA[<strong>RESUMEN</strong><br /> <strong>Introducci&oacute;n: </strong>La estimulaci&oacute;n cortical directa (DCS) es una metodolog&iacute;a corrientemente usada para localizar &aacute;reas del lenguaje en intervenciones quir&uacute;rgicas que incluyan resecciones.<br /> La estimulaci&oacute;n magn&eacute;tica transcraneana repetitiva (rTMS) a demostrado tambi&eacute;n su capacidad para inducir alteraciones transitorias. Recientemente el desarrollo del Sistema de Navegaci&oacute;n de TMS asegura precisa localizaci&oacute;n del sitio estimulado.<br /> El objetivo del trabajo es estudiar la confiabilidad de la estimulaci&oacute;n magn&eacute;tica transcraneal repetitiva navegada (nrTMS) en la localizaci&oacute;n de los sitios del lenguaje.<br /> <strong>M&eacute;todos:</strong> Once pacientes seleccionados para mapeo del lenguaje por DCS fueron evaluados pre-cirug&iacute;a con nrTMS. Los mapeos de lenguaje prequir&uacute;rgicos mediante nrTMS fueron comparados con DCS.<br /> <strong>Resultados: </strong>Un total de 25 nrTMS sitios del lenguaje y 38 DCS fueron localizados.<br /> La sensibilidad y la especificidad obtenida fue de 88.4 y 95.6, respectivamente. La distancia media fue evaluada en 4,5mm.<br /> <strong>Conclusiones:</strong> Los dispositivos de nrTMS permiten la identificaci&oacute;n de las &aacute;reas corticales del lenguaje. Con un alto grado de concordancia con el mapeo TMS. La nrTMS se muestra como una herramienta de inter&eacute;s en la investigaci&oacute;n y aplicaci&oacute;n pr&aacute;ctica en la funci&oacute;n del lenguaje.

    <dcterms:abstract><![CDATA[<p><strong>RESUMEN</strong><br /> El tratamiento de la Enfermedad Metast&aacute;sica Cerebral &uacute;nica es paliativo y multimodal desconoci&eacute;ndose con certeza la modalidad o combinaci&oacute;n terap&eacute;utica &oacute;ptima. Se plante&oacute; como objetivo determinar las diferencias entre la Radioterapia Holocraneal, Radiocirug&iacute;a, y Resecci&oacute;n Quir&uacute;rgica en cuanto a la Sobrevida Global, Sobrevida Con Independencia Funcional, Control Local, Muerte Neurol&oacute;gica y Neurocognici&oacute;n en los pacientes con enfermedad metast&aacute;sica cerebral &uacute;nica con tumor primario controlado. Se realiz&oacute; un estudio retrospectivo del tipo revisi&oacute;n sistem&aacute;tica cualitativa. Se incluyeron Ensayos Cl&iacute;nicos Aleatorizados que compararon la Cirug&iacute;a (con o sin Radioterapia Holocraneal), con la Radiocirug&iacute;a (con o sin Radioterapia Holocraneal) en la Enfermedad Metast&aacute;sica Cerebral &Uacute;nica independientemente de la localizaci&oacute;n del tumor primario. La b&uacute;squeda encontr&oacute; inicialmente 971 art&iacute;culos, de ellos 19 Ensayos Cl&iacute;nicos Aleatorizados. Al aplicar la herramienta de riesgo de sesgos de Cochrane se deriv&oacute; una muestra de 14 Ensayos Cl&iacute;nicos que presentaron bajo riesgo de sesgos. La combinaci&oacute;n de RQ y RTH ofreci&oacute; mayor SG que la RTH sola. La combinaci&oacute;n de RTH y RC ofreci&oacute; un mejor CL que la RQ y RTH. La combinaci&oacute;n de RTH Y RC ofreci&oacute; un mejor CL y SG que la RTH sola. No se encontraron diferencias significativas entre la RTH y RC versus RC sola. Los resultados en cuanto a la neurocognici&oacute;n y SIF fueron inconsistentes. El tratamiento &oacute;ptimo de los pacientes con EMC a&uacute;n no est&aacute; bien definido constituyendo a&uacute;n un tema controvertido.</p>

<p><strong>ABSTRACT</strong><br /> The treatment of Isolated Cerebral Metastatic Disease is both multimodal and palliative. At present, the optimal treatment protocol is unknown. The objective of the present study was to determine outcome differences between Whole Brain Radiotherapy (WBRT), Radiosurgery (RS), and Surgical Resection (SR) or a combination of them, regarding Global Survival, Functional Independent Survival, Local Control, Neurological Death &amp; Cognitive Status in patients with a unique cerebral metastasis and a controlled primary tumor. A retrospective study with a systematic qualitative literature review was performed. Randomized clinical trials comparing surgery (with or without whole brain radiotherapy), disregarding the localization of the primary tumor, were searched, resulting in 971 studies, only 19 of them being randomized. After applying Cochrane&acute;s Risk of Bias Tool, only 14 studies showed a low risk of bias. The combination of SR &amp; WBRT showed a longer survival, while WBRT &amp; RS showed a better local control when compared with SR &amp; WBRT. No statistical differences where found between WBRT &amp; RS versus RS alone. Results regarding Cognitive Status &amp; Functional Independent Survival were inconsistent. The optimal treatment in Isolated Metastatic Cerebral Disease still remains controversial.</p>

    <dcterms:abstract><![CDATA[<strong>RESUMEN</strong><br /> <strong>Objetivo:</strong> describir, paso a paso, la realizaci&oacute;n de un abordaje pterional (AP).<br /> <strong>Descripci&oacute;n:</strong> Posici&oacute;n: El paciente es colocado en dec&uacute;bito dorsal, con la cabeza rotada contralateral y deflexionada. Incisi&oacute;n: se extiende desde la l&iacute;nea media hasta el borde inferior del arco cigom&aacute;tico, 1 cm adelante del trago. Disecci&oacute;n interfascial: tiene varios referentes anat&oacute;micos: la arteria temporal superficial, el reborde orbitario y al arco cigom&aacute;tico en su porci&oacute;n inferior. La incisi&oacute;n se inicia en la l&iacute;nea temporal superior, 2 cm posterior del reborde orbitario, y se extiende en direcci&oacute;n al sector medio del arco cigom&aacute;tico. Desinserci&oacute;n del m&uacute;sculo temporal: se procede a realizar un corte muscular hasta alcanzar el plano &oacute;seo, y se realiza una disecci&oacute;n subperi&oacute;stica. Craneotom&iacute;a: la remoci&oacute;n &oacute;sea debe lograr una exposici&oacute;n suficiente de la fisura silviana, con mayor exposici&oacute;n del l&oacute;bulo frontal; as&iacute;, deben exponerse los giros frontales medio e inferior y el giro temporal superior. Apertura dural: en dos colgajos, uno frontal y otro temporal.<br /> <strong>Conclusi&oacute;n: </strong>el AP constituye a&uacute;n hoy d&iacute;a una t&eacute;cnica actual y vigente, que se resiste a ser olvidada, cuya aplicaci&oacute;n juiciosa permite acceso a un gran numero de patolog&iacute;as de la base de cr&aacute;neo anterior y media.

<p><strong>ABSTRACT</strong><br /> <strong>Objective: </strong>the aim of this study is to describe, step by step, the pterional approach.<br /> <strong>Description:</strong> position: the patient is placed supine, and the head rotated and also deflected. Incision: from the midline to de zygomatic arch, 1 cm in front of the tragus. Interfascial dissection: the landmarks: superficial temporal artery, orbital rim and zygomatic arch. The incision started at the level of the superior temporal line, 2 cm posterior to the orbital rim, and is pointed to the middle portion of the zygomatic arch. Temporal muscle displacement: after a transversal section of the upper portion of the muscle, it is detached in a subperiosteal fashion. Craniotomy: the osseous removal should expose the sylvian fissure and the middle and inferior frontal gyrus and also the superior temporal giri. Dural opening: in two flaps (frontal and temporal).<br /> <strong>Conclusion:</strong> the pterional approach is still, nowadays, a valid and current technique. This approach allows treating many lesions located in the anterior and middle cranial fossa.</p>

    <dcterms:abstract><![CDATA[<p><strong>RESUMEN</strong><br /> <strong>Objetivo: </strong>Realizar osteotom&iacute;as cervicales en preparados cadav&eacute;ricos, siguiendo la clasificaci&oacute;n moderna de 7 grados seg&uacute;n Ames y colaboradores, tomando fotos 3D para poner en evidencia la magnitud de resecci&oacute;n &oacute;sea de cada uno de los subtipos.<br /> <strong>Material y M&eacute;todos: </strong>Se utilizaron dos preparados cadav&eacute;ricos formolizados con inyecci&oacute;n vascular, realiz&aacute;ndose im&aacute;genes fotogr&aacute;ficas en 3 dimensiones de los mismos. Las fotograf&iacute;as fueron tomadas con una camara Nikon D90, con lente 50 mm Af 1.8G, flash Nikon SB700, y una barra regulable para fotograf&iacute;a. Se realiz&oacute; sobre las preparaciones cadav&eacute;ricas la disecci&oacute;n cervical con incisi&oacute;n en l&iacute;nea media posterior y abordaje por v&iacute;a anterior segun Smith y Robinson. Se efectu&oacute; la exposici&oacute;n muscular y esquelitizaci&oacute;n &oacute;sea con exposici&oacute;n de l&aacute;minas, ap&oacute;fisis espinosas, facetas articulares, ligamentos, discos, ap&oacute;fisis unciformes y cuerpos vertebrales. Mediante la utilizaci&oacute;n de un drill neum&aacute;tico de alta velocidad se realizaron 8 osteotom&iacute;as, 4 por v&iacute;a posterior y 4 por v&iacute;a anterior.<br /> <strong>Resultados: </strong>Las osteotom&iacute;as realizadas por v&iacute;a anterior fueron la discectom&iacute;a anterior completa (denominada osteotom&iacute;a grado I anterior), la corpectom&iacute;a parcial o total incluyendo discectom&iacute;a superior e inferior (denominada osteotom&iacute;a grado III), la resecci&oacute;n completa de la uni&oacute;n uncovertebral o articulaci&oacute;n de Luschka (denominada osteotom&iacute;a grado IV) y la resecci&oacute;n vertebral completa o espondilectom&iacute;a (denominada osteotom&iacute;a grado VII). Por v&iacute;a posterior, se realizaron la facetectom&iacute;a parcial (denominada osteotom&iacute;a grado I posterior), la facetectom&iacute;a total u osteotom&iacute;a de Ponte (denominada osteotom&iacute;a grado II), la osteotom&iacute;a de apertura angular (denominada osteotom&iacute;a grado V) y la osteotom&iacute;a de cierre angular o de sustracci&oacute;n pedicular (denominada osteotom&iacute;a grado VI). Las im&aacute;genes fotogr&aacute;ficas obtenidas fueron procesadas con los siguientes softwares con t&eacute;cnica anagl&iacute;fica: Anaglyph Maker versi&oacute;n 1.08 y StereoPhoto Maker versi&oacute;n 4.54.<br /> <strong>Discusi&oacute;n:</strong> Las osteotom&iacute;as vertebrales constituyen gestos quir&uacute;rgicos &uacute;tiles para la correcci&oacute;n de las deformidades espinales cervicales. A pesar de las distintas variantes t&eacute;cnicas de las mismas, no exist&iacute;a hasta hace poco un sistema que permitiera su nomenclatura y clasificaci&oacute;n. Ames y colaboradores proponen en 2013 una nomenclatura para este tipo de maniobras, clasific&aacute;ndolas en 7 grupos con distintos. El aporte de la anatom&iacute;a en 3D permiti&oacute; mejorar la compresi&oacute;n del grado de resecci&oacute;n &oacute;sea necesario para cada tipo de osteotom&iacute;a, y visualizar las estructuras nerviosas y vasculares en riesgo en cada tipo de abordaje.</p>

<p><strong>ABSTRACT</strong><br /> <strong>Objective:</strong> To perform cervical osteotomies in cadaveric specimens, following the new classification of Ames et al. 3D pictures were taken to show the amount of bone resection on each subtype. <br /> <strong>Material &amp; methods: </strong>Using two formolized cadaveric specimens with vascular injection, we took 3D pictures of osteotomies following the Ames et al classification of cervical osteotomies. The pictures were taken with a Nikon D90 camera, with a 50 mm lens Af 1.8G, Nikon SB700 flash, and an adjustable titanium frame designed to take 3D pictures. Anterior cadaveric dissections were made based on the Smith &amp; Robinson technique. We also performed a posterior approach to expose laminar surfaces, spinous processes, facets complexes, ligaments, discs, uncovertebral joints and vertebral bodies. With the aid of a pneumatic drill, 8 osteotomies (4 anterior and 4 posterior) were progressively made and pictured.<br /> <strong>Results:</strong> The anterior osteotomies were: discectomy, corpectomy, discectomy with uncovertebral resection and spondilectomy. Posterior osteotomies were: partial facetectomy, complete facetectomy (Ponte), open wedge osteotomy and closing wedge osteotomy (pedicle substraction). Pictures were processed and fused with Anaglyph Maker 1.08 and StereoPhoto Maker 4.54.<br /> <strong>Conclusions:</strong> Cervical osteotomies are useful surgical maneuvers to correct spinal deformities. 3D anatomy helps to understand the degree of bone resection needed to make each osteotomy, exposing nervous and vascular structures at risk in these procedures.</p>

    <dcterms:abstract><![CDATA[<strong>RESUMEN</strong><br /> <strong>Objetivo: </strong>Analizar en forma prospectiva la viabilidad de una neurorrafia mediante t&eacute;cnicas microquir&uacute;rgicas, en un modelo experimental con diferentes grados crecientes de p&eacute;rdida de tejido nervioso perif&eacute;rico.<br /> <strong>Introducci&oacute;n:</strong> Para reparar un nervio perif&eacute;rico que tiene p&eacute;rdida de tejido, cl&aacute;sicamente este defecto se suple por un injerto aut&oacute;logo. Sin embargo, se produce comorbilidad en el sitio dador y sus resultados siempre son inferiores a la sutura directa sin tensi&oacute;n. Existe una opci&oacute;n para evitar el uso de injertos cuando el defecto es escaso, colocando puntos epineurales distales (PED) a la neurorrafia, eliminando as&iacute; la tensi&oacute;n en dicha uni&oacute;n.<br /> <strong>Materiales y m&eacute;todos:</strong> Se utilizaron 40 ratas Wistar, dividi&eacute;ndose aleatoriamente en 4 grupos. Bajo anestesia general se abord&oacute; al nervio ci&aacute;tico y se efectu&oacute; secci&oacute;n trasversal y sutura simple con nylon 10.0 al grupo A (control). Se realiz&oacute; ex&eacute;resis de 2 mm de nervio al grupo B, de 4 mm al grupo C y de 6 mm al grupo D; para luego realizar PED. Se realizaron determinaciones de &iacute;ndice de funci&oacute;n ci&aacute;tico (an&aacute;lisis de las huellas), velocidad de conducci&oacute;n (electrofisiolog&iacute;a) e &iacute;ndice de regeneraci&oacute;n (histopatolog&iacute;a) para evaluar la viabilidad de la neurorrafia. Se confrontaron los diferentes grupos planteados con ANOVA, considerando significativo un valor de p &lt; 0.05.<br /> <strong>Conclusiones</strong>:La neurorrafia simple no evidencia diferencias estad&iacute;sticamente significativas con la reparaci&oacute;n de 2mm de p&eacute;rdida de tejido mediante PED en la rata Wistar.

<p><strong>ABSTRACT</strong><br /> <strong>Objective:</strong> To analyze, in a prospective way, the viability of a neurorraphy by a microsurgical technique, in an experimental model with different increasing grades of peripheral nerve tissue loss.<br /> <strong>Introduction:</strong> In order to repair a peripheral nerve that has experienced some grade of substance loss, autologous grafts have been used by most neurosurgeons. However, comorbidities in the donor site are produced, and the results obtained are always inferior compared to the ones achieved by using a direct suture without tension. There is an option to avoid using grafts when the defect is scarce, which is the confection of distal epineural sutures (DES) to the neurorraphy, discarding any tension in this junction site.<br /> <strong>Materials and methods:</strong> We have used 40 Wistar rats, randomly separated into 4 groups. In &lsquo;Group A&rsquo;, under complete anesthesia, the sciatic nerve was dissected and transversely sectioned and then sutured with a 10.0 nylon suture. Furthermore we made a 2 mm extirpation in &lsquo;Group B&rsquo;, a 4 mm one in &lsquo;Group C&rsquo; and a 6 mm one in &lsquo;Group C&rsquo;, in order to perform a DES technique. Our group also ran a sciatic nerve function test (footprint analysis), conduction speed (by electrophysiology), and even determined the nerve regeneration index (histopathology) to estimate the viability of the neurorraphy. The different groups were confronted with ANOVA, considering a value of p&lt;0.05 as statistically significative.<br /> <strong>Conclusions: </strong>Simple neurorraphy exposed no statistically significative differences in comparison to the reparation of a 2 mm tissue loss with DES technique, in the Wistar rat model.</p>

    <dcterms:abstract><![CDATA[<strong>RESUMEN</strong><br /> <strong>Objetivo:</strong> Describir la anatomía microquirúrgica y los abordajes a la región temporal mesial (RTM), en relación a cavernomas de dicho sector<br /> <strong>Material y Método:</strong> Cinco cabezas de cadáveres adultos, fijadas en formol e inyectadas con silicona coloreada, fueron estudiadas. Además, desde enero de 2007 a junio de 2014, 7 pacientes con cavernomas localizados en la RTM fueron operados por el autor.<br /> <strong>Resultados:</strong> Anatomía: la RTM fue dividida en 3 sectores: anterior, medio y posterior. Pacientes: 7 enfermos con cavernomas de la RTM fueron operados por el autor. De acuerdo a la ubicación en la RTM, 4 cavernomas se ubicaron en el sector anterior, 2 cavernomas se localizaron en el sector medio y 1 cavernoma se ubicó en el sector posterior. Para el sector anterior de la RTM se utilizó un abordaje transsilviano-transinsular; para el sector medio de la RTM se utilizó un abordaje transtemporal (lobectomía temporal anterior); y para el sector posterior de la RTM se utilizó un abordaje supracerebeloso-transtentorial.<br /> <strong>Conclusión: </strong>Dividir la RTM en 3 sectores nos permite adecuar el abordaje en función a la localización de la lesión. Así, el sector anterior es bien abordable a través de la fisura silviana; el sector medio a través de una vía transtemporal; y el sector posterior por un abordaje supracerebeloso.

<p><strong>ABSTRACT</strong><br /> <strong>Objective: </strong>To describe the microsurgical anatomy and approaches to the mesial temporal region (MTR), in relation with cavernomas.<br /> Material and Method: Five adult cadaveric heads, fixed in formol and injected with colored silicon were studied. Since January 2007 and June 2014, the author operated 7 patients with cavernomas located in the MTR.<br /> <strong>Results:</strong> Anatomy: the MTR was divided in 3 portions: anterior, middle and posterior. Patients: the author operated 7 patients with MTR cavernomas. Four cavernomas were located in the anterior portion, 2 were located in the middle portion, and 1 cavernoma was located in the posterior portion. The transsylvian-transinsular approach was used for the anterior portion of the MTR; the transtemporal approach (anterior temporal lobectomy) was used for the middle portion of the MTR; and the supracerebellar-transtentorial approach was used for the posterior portion of the MTR.<br /> <strong>Conclusion: </strong>The idea of divide the MTR in 3 portions help to select the correct approach.</p>

    <dcterms:abstract><![CDATA[<p><strong>RESUMEN</strong><br /> El liderazgo tradicional, vertical y autoritario, se ha vuelto inadecuado porque ha sido desafiado por los cambios ocurridos en la sociedad actual, la oferta educativa, las generaciones actuales y la cantidad de conocimientos. La sociedad moderna, considerada &ldquo;l&iacute;quida&rdquo; por la falta de certezas y su constante cambio en forma y direcci&oacute;n, cuestiona la experiencia como un recurso v&aacute;lido para resolver los nuevos problemas. La gran oferta educativa impide el monopolio de una persona determinada en la formaci&oacute;n y capacitaci&oacute;n profesional. La generaci&oacute;n &ldquo;Y&rdquo; moldeada por las particularidades del entorno familiar actual y sobre todo por la tecnolog&iacute;a de la comunicaci&oacute;n, busca relaciones m&aacute;s directas e informales originando conflictos en las organizaciones autoritarias y jer&aacute;rquicas. La gran cantidad de conocimientos producidos por el desarrollo cient&iacute;fico y su fragmentaci&oacute;n, impiden que alguien pretenda saber todo y se convierta en la &uacute;nica fuente a la cual recurrir. Quiz&aacute;s la respuesta a estos desaf&iacute;os est&eacute; en el desarrollo de competencias blandas como compartir, facultar, empatizar y trabajar en equipo. El l&iacute;der tradicional, al no poder tener la exclusividad de la informaci&oacute;n y la formaci&oacute;n tendr&iacute;a que resignar protagonismo y crear organizaciones m&aacute;s horizontales para que todos los integrantes desarrollen sus capacidades y logren sus objetivos.</p>
<p><strong>Palabras clave:</strong> Competencias Blandas; Generaci&oacute;n Y; Liderazgo; Sociedad Moderna L&iacute;quida</p>
<p><strong>ABSTRACT</strong><br /> The traditional highly centralized and authoritarian leadership challenged by the changes occurred in present society, educational opportunities, current generations and knowledge increase, has rendered inadequate. Modern society, considered &ldquo;liquid&rdquo; for the lack of certainties and its constant change in form and direction, defies experience as a valid mean to solve new problems. The great educational offer prevents that only one person will have the exclusiveness of professional training. &ldquo;Y&rdquo; generation, shaped by the distinctive features of its familiar environment and mainly by communicational technology, looks for direct and informal relationships, creating conflicts in the more authoritarian and hierarchical organizations. After modern scientific development, the great increase in knowledge and fragmentation impedes that somebody would pretend to know everything and turn to be the only source to recur. Perhaps the answer to these challenges may be the development of soft competences as share, empowerment, empathize and team work. The traditional leader, after losing knowledge and training exclusivity, should have to resign prominence and create more horizontal organizations in which every member will develop his competences and fulfill his objectives.</p>

    <dcterms:abstract><![CDATA[<p><strong>RESUMEN</strong><br /> <strong>Objetivo:</strong> Exponer nuestra experiencia quir&uacute;rgica en el abordaje pterional resaltando los alcances y detalles t&eacute;cnicos de dicho procedimiento.<br /> <strong>Material y m&eacute;todo: </strong>Se realiz&oacute; un estudio descriptivo retrospectivo, analizando las historias cl&iacute;nicas de 145 pacientes intervenidos quir&uacute;rgicamente a trav&eacute;s de un abordaje pterional cl&aacute;sico o alguna de sus variantes, entre octubre de 2009 y octubre de 2012, en nuestro servicio. Se recabaron datos epidemiol&oacute;gicos y los relacionados a las diferentes patolog&iacute;as alcanzadas mediante esta v&iacute;a. Para una mejor interpretaci&oacute;n, las im&aacute;genes fueron adquiridas en 3D.<br /> <strong>Resultados:</strong> Durante dicho per&iacute;odo se realizaron 149 craneotom&iacute;as pterionales sobre un total de 145 pacientes, 4 de los cuales debieron ser sometidos a abordaje pterional bilateral. Fueron intervenidos 95 pacientes con aneurismas cerebrales, 9 de ellos con enfermedad aneurism&aacute;tica m&uacute;ltiple. Este abordaje permiti&oacute; el acceso para la resoluci&oacute;n quir&uacute;rgica de un total de 115 aneurismas, 37 del segmento comunicante de la arteria car&oacute;tida interna, 29 de la arteria cerebral media, 26 de la arteria comunicante anterior, 7 de la bifurcaci&oacute;n carotidea, 6 del segmento oft&aacute;lmico de la car&oacute;tida interna, 3 del segmento coroideo, 2 paraclinoideos y 1 de la bifurcaci&oacute;n de la arteria basilar. Cuatro aneurismas se resolvieron mediante by pass de alto flujo. As&iacute; mismo se logr&oacute; la ex&eacute;resis de 45 lesiones tumorales, 23 frontales, 5 temporales, 5 del ala del esfenoides, 3 insulares, 3 intraorbitarias, 3 macroadenomas de hip&oacute;fisis, 2 craneofaringiomas y 1 tumor del nervio &oacute;ptico. Por otra parte, 4 pacientes con malformaciones arteriovenosas fueron intervenidos mediante este abordaje, 2 de localizaci&oacute;n insular, 1 frontal y 1 temporal. Un cavernoma frontal tambi&eacute;n se resec&oacute; mediante esta v&iacute;a. Se estandarizaron los siguientes pasos para la realizaci&oacute;n del abordaje pterional: tricotom&iacute;a y marcaci&oacute;n, posicionamiento del paciente y su cabeza, incisi&oacute;n, disecci&oacute;n interfascial, secci&oacute;n y disecci&oacute;n subperi&oacute;stica del m&uacute;sculo temporal, craneotom&iacute;a, anclado dural, drilado y apertura dural.<br /> <strong>Conclusi&oacute;n:</strong> La craneotom&iacute;a pterional representa una importante v&iacute;a de acceso para la resoluci&oacute;n de un amplio espectro de patolog&iacute;as. El conocimiento acerca de los alcances y detalles t&eacute;cnicos son de utilidad en la pr&aacute;ctica neuroquir&uacute;rgica diaria, especialmente para los neurocirujanos en formaci&oacute;n.</p>

<p><strong>ABSTRACT</strong><br /> <strong>Objective:</strong> to report our surgical experience in the pterional approach, highlighting the extent and technical details of that procedure.<br /> <strong>Material and Method: </strong>we performed a retrospective study analyzing the medical records of 142 patients who went under surgery through a classic pterional approach or one of its variants, between October 2009 and October 2012. Epidemiological data was collected and also that related to the different pathologies achieved by this route. For a better interpretation, the images were taken in 3D.<br /> <strong>Results:</strong> during that period we performed 149 pterional craniotomies over a total of 145 patients, 4 of them underwent bilateral pterional approach. There were 95 patients with cerebral aneurysms, 9 of them with multiple aneurysmal disease. This approach allowed access for the surgical treatment of a total of 115 aneurysms, 37 of the communicating segment of the internal carotid artery, 29 of the medial cerebral artery, 26 of the anterior communicating artery, 7 of the carotid bifurcation, 6 of the ophthalmic segment of the internal carotid artery, 3 of the choroid segment, 2 paraclinoidal and 1 of the basilar artery bifurcation. Four were solved by high flow carotid-sylvian bypass. It was also achieved the excision of 45 tumors, 23 frontal, 5 temporal, 5 of the sphenoidal wing, 3 insular, 3 intraorbital, 3 pituitary macroadenomas, 2 craneopharingiomas and 1 optical nerve tumor. On the other hand, 4 patients with arteriovenous malformations went on surgery by this approach, 2 of insular location, 1 frontal and 1 temporal. A frontal cavernoma was also resected by this gateway. We formalized the following steps to perform the pterional approach: trichotomy and demarcation, patient and head positioning, incision, interfascial dissection, subperiostic section and dissection of the temporal muscle, craniotomy, dural attachment, drilling and dural opening. <br /> <strong>Conclusion:</strong> the pterional craniotomy is a major gateway for solving a wide spectrum of diseases. The knowledge about the extent and technical details of this pathway is essential in daily neurosurgical practice, especially for neurosurgical interns.</p>

    <dcterms:abstract><![CDATA[<p><strong>RESUMEN</strong><br /> <strong>Objetivo:</strong> Describir la anatom&iacute;a del fasc&iacute;culo de Meyer (FM) y los resultados del campo visual computarizado (CVC) y tractograf&iacute;a, por tensor de difusi&oacute;n (TTD) en la identificaci&oacute;n del compromiso de este fasc&iacute;culo en pacientes tratados quir&uacute;rgicamente por epilepsia refractaria. <br /> <strong>Introducci&oacute;n:</strong> Hasta un 80% de los pacientes con epilepsia temporo-mesial asociada a esclerosis hipocampal son refractarios a la medicaci&oacute;n. Para estos pacientes la cirug&iacute;a es un tratamiento bien establecido y efectivo. No obstante son frecuentes los defectos del campo visual por lesi&oacute;n del FM luego de este tipo de procedimientos. <br /> <strong>Materiales y m&eacute;todos:</strong> Se realiz&oacute; disecci&oacute;n de fibras blancas de tres cerebros humanos, fijados en formaldeh&iacute;do, mediante la t&eacute;cnica de Klingler, con el fin de reconocer los fasc&iacute;culos que conforman la v&iacute;a visual en la profundidad del l&oacute;bulo temporal. A su vez, se estudiaron 8 pacientes sometidos a lobectom&iacute;a temporal anterior y amigdalohipocampectom&iacute;a por esclerosis temporomesial, realiz&aacute;ndose TTD y CVC, al menos 3 meses despu&eacute;s de la cirug&iacute;a. Los individuos se clasificaron en cuatro grupos seg&uacute;n el defecto campim&eacute;trico y se realizaron distintas mediciones en tractograf&iacute;a y resonancia magn&eacute;tica. Finalmente se correlacionaron los resultados de las distintas variables y se realiz&oacute; una extensa revisi&oacute;n bibliogr&aacute;fica. <br /> <strong>Resultados:</strong> Mediante la disecci&oacute;n anat&oacute;mica se logr&oacute; identificar el FM como as&iacute; tambi&eacute;n el resto de los fasc&iacute;culos y estructuras relacionadas a la v&iacute;a visual en la profundidad del l&oacute;bulo temporal. Todos los pacientes presentaron alg&uacute;n grado de d&eacute;ficit campim&eacute;trico. En ning&uacute;n paciente se logr&oacute; identificar el borde anterior del FM en el lado no operado, no obstante, la mediana de la posici&oacute;n del FM en el hemisferio no intervenido quir&uacute;rgicamente (T-FM) fue de 29,6 mm. La mediana de la longitud medida desde el l&iacute;mite anterior de la fosa media hasta el borde posterior de la resecci&oacute;n temporal fue de 37,8 mm. La mediana de la distancia desde el l&iacute;mite anterior de la fosa media hasta el primer fasc&iacute;culo identificable de sustancia blanca (A-SBI) fue de 33mm. <br /> Conclusi&oacute;n: existe una considerable variaci&oacute;n interindividual en la extensi&oacute;n anterior del FM, por lo que la TTD focalizada en el l&oacute;bulo temporal es un m&eacute;todo potencialmente &uacute;til para evaluar el riego de defectos campim&eacute;tricos en pacientes sometidos a cirug&iacute;a resectiva a nivel temporal anterior.</p>

<p><strong>ABSTRACT</strong><br /> <strong>Objective: </strong>To describe the anatomy of the Meyer&acute;s loop (ML) and the results of computerized visual field (CVF) and diffusion tensor tractography (DTT) to identify the damage of this fascicle in patients surgically treated for refractory epilepsy secondary to mesial-temporal sclerosis. <br /> <strong>Introduction:</strong> Up to 80% of patients with temporo-mesial epilepsy associated with hippocampal sclerosis are refractory to medication. For these patients, surgery is a well established and effective treatment. However visual field defects are frequent by optic radiation&acute;s injury after these procedures. <br /> <strong>Materials and methods:</strong> We performed the dissection of white fibers on three human brains, previously fixed in formaldehyde, by Klingler&acute;s technique, to recognize the fascicles that make up the visual pathway in the depth of the temporal lobe. Then, eight patients submitted to anterior temporal lobectomy and amygdalohippocampectomy were studied performing CVF and TTD at least 3 months after surgery. Individuals were classified into four groups according to visual field defects and other measurements in magnetic resonance imaging and tractography. Finally the results of the different variables were correlated and an extensive review of literature was performed. <br /> <strong>Results:</strong> Using anatomical dissection the ML was identified as well as the rest of the fascicles and related structures to the visual pathway in the depth of the temporal lobe. All patients had some degree of visual field deficits. We couldn&acute;t identify the leading edge of ML on the healthy side, however, the median position of the ML in the hemisphere without surgery (T-ML) was 29.6 mm. The median length measured from the anterior limit of the middle fossa to the posterior edge of the temporal resection was 37.8 mm. The median distance from the anterior limit of the middle fossa to the first identifiable bundle of white matter (A-SBI) was 33mm. <br /> <strong>Conclusion:</strong> There is wide interindividual variation in the anterior extent of the ML, so the TTD focused on the temporal lobe is a potentially useful to assess individual risk of visual field defects in patients undergoing anterior temporal lobe surgery.</p>

    <dcterms:abstract><![CDATA[<strong>RESUMEN</strong><br /> <strong>Objetivo:</strong> Analizar el lado de abordaje pterional elegido teniendo en cuenta la disposici&oacute;n del segmento postcomunicante de las arterias cerebrales anteriores (A2) en el plano coronal y sus implicancias quir&uacute;rgicas.<br /> <strong>Material y M&eacute;todo:</strong> Estudio observacional descriptivo retrospectivo. Se analizaron 24 pacientes con aneurismas de la arteria comunicante anterior de variedad superior y antero-superior, operados en el per&iacute;odo 2009-2014. Se operaron 22 pacientes con Hemorragia Subaracnoidea (91.67%) y 2 pacientes con aneurismas incidentales (8.33%). Se estudi&oacute; la dominancia del segmento precomunicante (A1), la variedad de A2 (abierta o cerrada) y sus consecuencias quir&uacute;rgicas: necesidad de aspiraci&oacute;n del girus recto (AGR), utilizaci&oacute;n de clip fenestrados, presencia de contusi&oacute;n debido a retracci&oacute;n cerebral, isquemia en territorio de perforantes (ITP) y cuello remanente.<br /> <strong>Resultados:</strong> De los 24 pacientes estudiados, 12 (50%) presentaban una variedad A2 abierta. Tan solo 1 requiri&oacute; AGR, 1 sufri&oacute; ITP y 2 contusiones, sin necesidad de utilizar clips fenestrados ni tampoco registrarse alg&uacute;n cuello remanente. Los 12 pacientes restantes (50%) presentaron una variedad A2 cerrada. En este grupo fue necesario AGR en 8 casos, utilizaci&oacute;n de clip fenestrados en 3 casos, se registraron 3 ITP, 3 contusiones y 1 con cuello remanente (p=0.01).<br /> <strong>Conclusi&oacute;n:</strong> Creemos que abordar a los aneurismas de variedad superior y antero-superior del lado en el que las A2 representan una variedad abierta, permite lograr una correcta exposici&oacute;n anat&oacute;mica con el consiguiente clipado aneurism&aacute;tico adecuado y reducci&oacute;n de las complicaciones quir&uacute;rgicas.
<p><strong>Palabras clave:</strong> Arteria Comunicante Anterior; Aneurisma Intracraneal; Abordaje Pterional</p>
<p><strong>ABSTRACT</strong><br /> <strong>Objective: </strong>To analyze the chosen side in a pterional approach based on the position of the postcommunicating segment of anterior cerebral artery (A2) in a coronal plane, and its surgical requirements and complications.<br /> <strong>Material and Method:</strong> A descriptive observational retrospective study has been designed. We analyzed 24 patients with anterior communicating artery aneurysms projecting superior and supero-anterior, who underwent microsurgical clipping between 2009-2014. This study includes 22 subarachnoid hemorrhages (91.67%) and 2 incidental aneurysms (8.33%). We studied the dominancy of the precommunicating segment (A1), A2 plane (open or closed) and the surgical requirements: gyrus rectus aspiration (GRA) or the need of fenestrated clips, and complications: cerebral contusion due to brain retraction, perforators' ischemia (PI) and residual neck.<br /> <strong>Results:</strong> Out of the 24 patients, 12 (50%) were A2 open plane. Only 1 required GRA, 1 suffered perforators' ischemia and 2 had cerebral contusion. No fenestrated clip was used, and there was no residual neck. The remaining 12 patients (50%) had an A2 close plane. In this group, GRA was necessary in 8 cases and the use of fenestrated clip in 3. Perforators' ischemia was present in 3 cases, whereas another 3 patients suffered cerebral contusion and 1 had a residual neck (p=0.01).<br /> <strong>Conclusion:</strong> We suggest that approaching anterior cerebral arteries aneurysms projecting superior and supero-anterior from an A2 open plane, allows an optimal anatomical exposure view with an adequate aneurysm clipping and reducing surgical complications.</p>

    <dcterms:abstract><![CDATA[Introducción: el abordaje supracerebeloso infratentorial fue descripto originalmente por Sir Victor Horsley, siendo posteriormente adaptado por Stein quien aplica la técnica microquirúrgica mejorando los resultados de las cirugías de la región pineal.<br />
Objetivos: resaltar y sistematizar las indicaciones, detalles técnicos-anatómicos en el abordaje supracerebeloso infratentorial en base a nuestra experiencia quirúrgica y la revisión de la anatomía microquirúrgica de la región Pineal.<br />
Material y métodos: se realizó un estudio descriptivo retrospectivo analizando las historias clínicas de 7 pacientes intervenidos quirúrgicamente a través de un abordaje supracerebeloso infratentorial, entre septiembre 2010 hasta septiembre 2013 en nuestro servicio. Las imágenes intraquirúrgicas y de preparados anatómicos fueron adquiridas en 3D. La revisión bibliográfica se realizó en Pub Med utilizando las palabras claves: Abordaje Supracerebeloso Infratentorial; Región Pineal; Craniectomía Suboccipital.<br />
Resultados: durante el período 2010-2013 fueron intervenidos 7 pacientes. A todos se le practicó un abordaje supracerebeloso infratentorial. Fueron tratados 5 tumores de la región pineal, 1 glioma del culmen cerebeloso y 1 MAV de la fisura cerebelo mesencefálica.<br />
Se estandarizaron los siguientes pasos para la realización del abordaje supracerebeloso infratentorial de Stein: preparación prequirúrgica, posición sentado, posición de la cabeza, marcación y antisepsia cutánea, colocación de campos estériles, incisión de piel y tejido celular subcutáneo, disección de plano muscular, craneotomía, apertura dural, preparación del corredor supracerebeloso, disección intradural y anatomía microquirúrgica de la región pineal y consideraciones sobre el cierre.<br />
Conclusiones: se sistematizó el abordaje supracerebeloso infratentorial con el que pudimos acceder a tumores pineales y también a lesiones vasculares en la región. En todos los casos la exposición anatómica fue suficiente para tratar en forma adecuada las patologías mencionadas, con mínima retracción de las estructuras del SNC.]]></dcterms:abstract>
    <dcterms:tableOfContents><![CDATA[Introduction: even though Horsley was the first one to describe the supracerebellar infratentorial approach, it was Stein who adapted it to microsurgical techniques in an attempt to improve the results of surgical procedures on the pineal gland. <br />
Objectives: to enhance the indications and technical details of the supracerebellar infratentorial approach, based upon our experiences, we review the microsurgical anatomy of the pineal region that is exposed via this approach.<br />
Materials and methods: a retrospective descriptive study was conducted by analyzing the records of seven patients who had been operated on using this approach at our institution between September 2010 and September 2013. The images shown were obtained in 3D.<br />
Results: the indications for surgery in these seven patients were a pineal gland tumor in five patients, and a culmen glioma and mesencephalic-fissure AVM in one patient each. The following steps were standardized according to Stein’s description of the supracerebellar infratentorial approach: pre-surgical preparation, sitting position, head position, incision drawing and anti-sepsis, surgical field, collocation, skin and hypodermis incision, muscular dissection, hemostatic control, craniotomy, dural opening, supracerebellar corridor preparation, intradural dissection, microsurgical anatomy study, and considerations regarding closure. <br />
Conclusions: via this approach, we not only have been able to access pineal gland tumors but also vascular lesions in this region. The anatomical exposure achieved was enough to treat these lesions successfully, with minimal manipulation of the CNS.]]></dcterms:tableOfContents>

    <dcterms:title><![CDATA[Abordaje retrosigmoideo]]></dcterms:title>
    <dcterms:subject><![CDATA[Neurocirugía]]></dcterms:subject>
    <dcterms:description><![CDATA[Nota Técnica]]></dcterms:description>
    <dcterms:abstract><![CDATA[Objetivo: describir en forma detallada, paso a paso, la realización de un abordaje retrosigmoideo.<br />
Descripción: posición: existen 3 posiciones descritas para la realización de este abordaje, semisentada, decubito dorsal y en banco de plaza. Incisión: se extiende desde la parte superior del pabellón auricular hasta 2 cm por debajo del vertice mastoideo, y 1 cm medial a la ranura digástrica. Disección de partes blandas: se realiza una disección subperiostica, teniendo especial cuidado con la vena hemisaria mastoidea (posible fuente de embolia aérea). Craniectomía: es necesario identificar previamente algunos puntos anatómicos de referencia para la ubicación de los senos transverso y sigmoides. En la etapa final de la remoción ósea, se procede al fresado de la porción más superior y lateral del abordaje, con la necesaria exposición de la porción inferior del seno transverso y de la porción medial del seno sigmoides. Apertura dural: se realiza una apertura en forma de letra “C” (lado izquierdo), o letra “C invertida” (lado derecho), con base medial, comenzando en la porción superior y medial de duramadre expuesta. Disección microquirúrgica: dependiendo de la ubicación de la patologia a abordar se debe realizar una retracción gentil del hemisferio cerebeloso hacia medial. En la mayoría de los casos es necesario abrir la cisterna cerebelobulbar, con el objeto de evacuar LCR.<br />
Conclusión: el refinamiento alcanzado actualmente hace que el abordaje retrosigmoideo sea el más utilizado para el tratamiento de las múltiples patologías ubicadas en la región del ángulo pontocerebeloso. El acceso que proporciona esta vía a la mayoría de los nervios craneales que se encuentran en la fosa posterior, y a sus complejos neurovasculares correspondientes, lo convierte en un abordaje de obligatorio aprendizaje para todo neurocirujano.]]></dcterms:abstract>
    <dcterms:tableOfContents><![CDATA[Objective: the aim of this paper is to describe, step by step, the retrosigmoid approach to accessing the cerebellopontine angle (CPA).<br />
Description: patient position: three potential positions have been described for this approach: semi-sitting, dorsal decubitus and park bench. Incision: The incision extends from the top of the ear to 2 cm below the mastoid apex, and 1 cm medial to the digastric groove. Soft tissue dissection: A subperiosteal dissection is performed, taking special care to avoid the mastoid emissary vein. Craniotomy: At the outset, it is necessary to identify certain anatomical landmarks to localize the transverse and sigmoid sinuses. Dural opening: The dural incision is made in the shape of the letter “C” on the left side or an inverted letter “C” on the right. Microsurgical dissection: Depending on the location of the pathology being treated, it may be necessary to perform gentle cerebellar retraction medially.<br />
Conclusions: the refinements now achieved with the retrosigmoid approach make it the most widely-used approach for the treatment of lesions located within the CPA. The access provided by this approach to the vast majority of the cranial nerves in the posterior fossa, as well as their neurovascular complexes, makes it a mandatory approach for all neurosurgeons to learn.]]></dcterms:tableOfContents>

    <dcterms:abstract><![CDATA[Introducción: la Aspergilosis Invasiva (AI) del Sistema Nervioso Central (SNC) es infrecuente y ocurre generalmente en pacientes inmunocomprometidos. Puede presentarse con cuadros de meningitis, aneurismas micóticos, infartos o abscesos. Es una infección con pronóstico reservado y puede afectar el SNC de forma primaria o secundaria a partir de un foco que se disemina por vía hematógena. Presentamos el caso de un paciente con AI con invasión primaria a nivel óseo y diseminación posterior al cerebro.<br />
Caso clínico: paciente masculino de 25 años con diagnóstico de leucemia linfática aguda en tratamiento quimioterápico que presentó neumonitis por metotrexate por lo que inicia tratamiento con corticoides. Posteriormente agregó cervicalgia y con el diagnóstico de osteomielitis cervical se realiza punción bajo tomografía computada (TC) sin aislarse gérmenes. Se colocó Halo Vest e inició tratamiento antibiótico empírico. Posteriormente presentó afasia de expresión secundaria a lesión frontal izquierda. Se realizó evacuación de absceso cerebral aislando A. fumigatus. El tratamiento antibiótico específico posterior permitió una buena respuesta clínica y radiológica.<br />
Conclusión: la presencia de lesiones en el SNC de pacientes inmunocomprometidos debe incluir a las micosis como diagnóstico diferencial. La evacuación quirúrgica permite llegar rápidamente al diagnóstico mejorando la respuesta posterior al tratamiento antibiótico. Para evaluar la respuesta terapéutica y posibles recaídas se debe realizar un seguimiento periódico clínico radiológico. ]]></dcterms:abstract>
    <dcterms:tableOfContents><![CDATA[Introduction: invasive aspergillosis (IA) of the central nervous system (CNS) is an uncommon condition that usually occurs in immunocompromised patients. This illness can manifest as meningitis, or as a micotic aneurism, stroke or abscess. The infection affects the CNS either primarily or, more often, secondarily via blood dissemination from a distant focus, and has a poor prognosis. We present a patient with IA primarily affecting the cervical bones, with later spread into the brain. <br />
Case report: a 25-year old male was receiving chemotherapy for acute lymphocytic leukemia when he developed pneumonitis secondary to methotrexate and was started on corticosteroids. He subsequently developed cervicalgia, prompting a needle biopsy of the fourth vertebrae, after which a diagnosis of osteomyelitis was made. Even though the biopsy culture was negative, empirical antibiotics were initiated. A parietal lobe lesion was treated surgically months later after the patient presented with three episodes of transient aphasia. After A. fumigatus grew in culture, the patient’s antibiotic regimen was changed to treat the specific agent with a good response.<br />
Conclusion: IA must be considered a possibility whenever an immunocompromised patient presents with a new brain lesion. These lesions require surgical evacuation, a procedure that allows for diagnostic confirmation and enhances prognosis. Appropriate anti-fungal therapy must be started as soon as the diagnosis is confirmed. In addition, the patient’s neurological exam must be repeated and images obtained periodically to monitor treatment and detect possible recurrences.]]></dcterms:tableOfContents>

    <dcterms:abstract><![CDATA[Objetivo: describir la resolución quirúrgica de un caso de hernia medular transdural.<br />
Descripción: Paciente de 33 años de edad con antecedentes de historia progresiva de debilidad motora de 6 meses de evolución. Al examen se constató paraparesia asimétrica con anestesia por debajo del dermatoma T8, constituyendo un síndrome de Brown Sequard. En las imágenes de resonancia magnética se observó herniación ventral de la medula espinal a nivel T7-8.<br />
Intervención: se realizó abordaje extrapleural posterolateral a la columna torácica. Con técnica microquirúrgica se encontró el defecto dural en la duramadre ventral, y la herniación medular correspondiente en el nivel T7-8. Se encontraron, asimismo, cuerpos osteocartilaginosos en dicho nivel. Se procedió a disecar la interface médula espinal del defecto dural, ampliando el mismo y liberando la médula espinal, sin necesidad de retracción medular por esta vía. Luego de reponer en su correcta posición a la médula se procedió al cierre dural primario con microsutura.<br />
Conclusión: las hernias medulares transdurales torácicas el abordaje posterolateral extracavitario es una opción válida, permitiendo tener una mejor visión microquirúrgica de la duramadre ventral, con la ventaja de no requerir tracción ni rotación neural como se requiere en el caso de la laminectomía tradicional. ]]></dcterms:abstract>
    <dcterms:tableOfContents><![CDATA[Objective: to describe the successful surgical repair of idiopathic transdural spinal cord herniation<br />
Description: the patient was a 33-year-old female with a 6-month history of progressive motor weakness. Neurologic examination revealed asymmetric paraparesis with anesthesia below the T8 dermatome, consistent with Brown-Séquard Syndrome. Magnetic resonance imaging (MRI) of the thoracic spine demonstrated a spinal cord that was displaced and herniated ventrally, with loss of the normal overlying cerebrospinal fluid space between T7 and T8. <br />
Intervention: a lateral extra-pleural approach was used to access the thoracic spine. With microsurgery, we identified a defect in the ventral dura, with transdural spinal cord herniation. Osteocartilaginous bodies also were observed. Microsurgical un-tethering of the spinal cord herniation was performed along with primary repair of ventral dural defect. To un-tether the herniation without spinal cord manipulation, an incision was made on one side of the defect; with this maneuver, the diameter of the defect was increased, avoiding any traction on neural structures. Once the herniated spinal cord was freed, the ventral dura was repaired via non-interrupted closure.<br />
Conclusion: the posterolateral extra-pleural approach is a good option to treat spinal cord herniation in the thoracic spine, providing a better optical corridor to detect ventral dural defects than with a thoracic laminectomy, and avoiding any neural traction or rotation.]]></dcterms:tableOfContents>

    <dcterms:tableOfContents><![CDATA[Introduction: idiopathic spinal cord herniation (ISCH) is an infrequent cause of progressive myelopathy with a variable clinical presentation. As such, the diagnosis is frequently made by means of magnetic resonance imaging (MRI). Treatment is largely surgical with generally good outcomes.<br />
Case Reports: we present two cases. The first was a 57-year old female with a year-long history of numbness in all extremities and weakness in the right side of her body, in whom the diagnosis of ISCH was made by MRI and CT myelography. The second patient was a 46-year old female with neck pain and lower limb paresthesia. Additional MRI studies revealed ISCH. Due to the non-progressive nature of symptoms, conservative management was provided to both patients.<br />
Conclusion: idiopathic spinal cord herniation is a pathology that must be considered among differential diagnoses in patients with clinical evidence of progressive spinal compromise. An accurate diagnosis and prompt treatment often leads to a good clinical outcome. ]]></dcterms:tableOfContents>

<p><strong>COMENTARIO</strong><br /> La hernia medular idiop&aacute;tica (HMI) es un hecho poco frecuente, de patogenia desconocida (aunque existen varias hip&oacute;tesis al respecto) que se caracteriza por un desplazamiento ventral de la m&eacute;dula espinal a trav&eacute;s de un defecto dural ventral o ventro-lateral, predominantemente en la columna tor&aacute;cica.<sup>1-3</sup><br /> En una revisi&oacute;n reciente1 se identificaron 159 tratados con cirug&iacute;a y 15 casos tratados sin cirug&iacute;a. La presencia de progresi&oacute;n en los s&iacute;ntomas mielop&aacute;ticos ser&iacute;a el motivo por el cual se indicar&iacute;a la cirug&iacute;a, con una evoluci&oacute;n favorable en algo m&aacute;s del 70% de los casos reportados.<br /> La mayor&iacute;a de las publicaciones son sobre casos aislados o series peque&ntilde;as de casos (no m&aacute;s de 12).<sup>1-3</sup> Su historia natural no es muy conocida. Debido a ello, resulta dif&iacute;cil establecer una conducta de acuerdo con los postulados de la medicina basada en la evidencia. Las decisiones terap&eacute;uticas depender&iacute;an, entonces, del criterio m&eacute;dico, las experiencias pasadas y/o el estado del paciente en cada caso.<br /> Los autores, Jacobo y col., han descripto 2 nuevos casos que, tanto en la cl&iacute;nica como en las im&aacute;genes, no se diferencian de los ya publicados. No explicaron por qu&eacute; una HMI a nivel dorsal producir&iacute;a compromiso de los miembros superiores; ser&iacute;a interesante conocer c&oacute;mo podr&iacute;an haberse afectado los dermatomas cervicales (&iquest;tracci&oacute;n?, &iquest;isquemia?) en los casos descriptos. <br /> Ellos optaron por no operarlos argumentando falta de evolutividad. Esta conducta tiene sustento en la bibliograf&iacute;a pero, de acuerdo con lo publicado recientemente, la decisi&oacute;n de no operar implica no mejorar en el 100% de los casos.1 Como los autores no hacen referencia al seguimiento, no sabemos durante cu&aacute;nto tiempo han permanecido estables. En la literatura, el seguimiento promedio de los casos no operados fue de 33 meses, per&iacute;odo durante el cual no hubo empeoramientos.<sup>1</sup><br /> La publicaci&oacute;n de casos como &eacute;ste, ayudan a mantenernos alertas sobre las patolog&iacute;as raras y a generar experiencia para saber c&oacute;mo conducirnos.</p>
