Abstract

Distal anterior cerebral artery aneurysms are infrequent. The most common location is at the bifurcation of the pericallosal and callosomarginal arteries. Cerebral artery anomalies can sometimes, at least partially, explain aneurysm formation in less common locations in relation to hemodynamic stress caused on the vascular wall. We report a very rare case of subarachnoid hemorrhage due to a ruptured frontopolar artery aneurysm as a part of an anomalous anterior cerebral artery complex that was, for the first time, treated with endovascular coiling.

Subarachnoid hemorrhage
Frontopolar artery

Resumen

Los aneurismas distribuidos distalmente en la circulación cerebral anterior son infrecuentes. La localización más habitual dentro de este tipo de aneurismas es la bifurcación entre las arterias pericallosa y callosomarginal. Las variantes anatómicas vasculares cerebrales pueden explicar, al menos en parte, la formación de aneurismas en localizaciones menos comunes en relación al estrés hemodinámico que ocasionan en la pared vascular. Describimos un caso infrecuente de hemorragia subaracnoidea debida a la rotura de un aneurisma en la arteria frontopolar y que forma parte de una variante anómala del complejo de la arteria cerebral anterior que ha sido por primera vez manejado mediante tratamiento endovascular.
