RESUMO
Objetivo: Describir el acceso quirúrgico a la fosa interpeduncular para la resección de cavernomas ubicados en situación ventromedial del mesencéfalo. Introducción: El abordaje ¨Pretemporal¨ contralateral con resección orbitocigomatica utilizando la via transilviana, permite abordar la cara ventral de la fosa interpeduncular para lesiones comprendidas entre la union diencefalo-mesencefálica y el surco ponto-mesencefálico. Materiales y Métodos: Datos de historia clínica, fotografías y videos obtenidos de un caso quirúrgico operado en nuestro servicio. Disecciones cadavéricas en 14 piezas anatómicas de tronco cerebral (9 siguiendo la técnica de Klingler y 5 piezas sin congelar, de modo comparativo), 23 especímenes inyectados describiendose los corredores quirúrgicos a la región, mas estudios complementarios. Discusión: La bibliografía internacional consultada propone el abordaje orbitocigomatico homolateral para lesiones situadas en la fosa interpeduncular. En nuestro caso elegimos el abordaje ¨Pretemporal¨ con resección orbito-cigomática contralateral dada la localización alta de la lesión y la disposición de su eje mayor (antero-posterior) en sentido opuesto, ofreciendo de este modo un mejor ángulo de ataque por esta vía propuesta. Conclusión: En nuestra experiencia el abordaje ¨Pretemporal¨ contralateral con orbitotomia y en ¨particular¨ la resección cigomática mejoró el ángulo de trabajo, desde inferior a superior y de lateral a medial, para alcanzar de este modo lesiones mesencefálicas ventro-mediales ¨altas¨ en el plano sagital, versus un acceso ¨Orbitocigomatico¨ clásico homolateral.

CONTEXT: Migration to the United States from Mexico is increasing every year. Mexican immigrants tend to be poor, uninsured, monolingual Spanish speakers without adequate access to appropriate medical care. As a further barrier, many are also undocumented. PURPOSE: This article describes a program developed to improve access to health care among Mexican immigrants in northern Colorado. METHODS: The program was implemented by a migrant/community health center in rural northern Colorado based on findings from an in-depth health needs survey of the target population. The program consists of community outreach services vertically integrated into the main medical clinics, which comprise Salud Family Health Centers. A mobile unit went to nontraditional areas identified by community workers as gathering places for Mexican immigrants. Services provided included preventive health care (screening for diabetes, hypertension, mental health problems, dental problems, and HIV); education; and primary care for acute problems. Patients were referred to a health care home for ongoing care. RESULTS: In the first 6 months, 1,553 Mexican immigrants were seen on the mobile unit. Hypertension and psychosocial problems were the most common problems in this population. Thirty-five percent of patients who received consultation in the mobile unit have visited any of the clinics for follow-up within the following year. CONCLUSIONS: A community-based mobile outreach program targeted toward Mexican immigrants can be effective in uncovering medical and mental illness and in directing patients to a health care home. This is an important first step in eliminating health disparities among this population.
