Resumen

Es universalmente aceptado que el polígono de Willis presenta variantes en su anatomía habitual, hasta en el 60% de los casos.

Algunas de éstas se asocian a malformaciones vasculares, como los aneurismas. El conocimiento de estas variantes anatómicas es de fundamental importancia con vistas al acto quirúrgico, con el fin de preservar arterias en topografía poco habituales y cuya lesión puede determinar secuelas invalidantes.

Los autores, en revisión anatómica de 192 hemisferios cerebrales, encuentran tres variantes del sector anterior del Polígono de Willis: arteria ácigos cerebral anterior, arteria mediana del cuerpo calloso y arteria cerebral media accesoria.

Se realiza la descripción anatómica de los hallazgos, la correlación con la angiografía y finalmente cómo influyeron estos cambios en el acto quirúrgico de aneurismas de las regiones implicadas.

Abstract

lt is worlwide accepted that in almost 60% of cases, anatomical variants in the Circle of Willis can be found.

Some of them are associated with vascular malformations such as aneurysms. The knowledge of these anatomical variants is of vital importance when facing surgery, being the aims to preserve arteries in unusual localisations, which when injured can determine invalidating sequelae.

The authors have reviewed 192 cerebral hemispheres, finding three variants in the anterior Circle of Willis: Azigos anterior cerebral artery; Median artery of the corpus callosum and accesory middle cerebral artery. The authors make an anatomical description of the findings, their angiographical correlation, and describe the influence of these changes during surgery of aneurysms in the involved regions.

Key words:
Circle of Willis
Accesory middle cerebral artery
Azigos anterior cerebral artery
Median artery of the Corpus Callosum
Vascular anatomy Cerebral aneurysms
