Abstract
Distal anterior cerebral artery aneurysms often rupture at a small size and are associated with overall higher operative morbidity relative to other anterior circulation aneurysms. This patient had an incidentally identified anterior cerebral artery proximal A2 segment fusiform aneurysm that did not respond to endovascular treatment and required open surgical management. The fusiform dilation was mobilized and isolated circumferentially within the interhemispheric fissure, and a Gore-Tex clip-wrapping was planned. A permanent clip was applied along the aneurysmal dilation parallel to the vessel directly prior to completing the wrapping to attempt to establish native flow dynamics through the aneurysmal segment. The clip-wrapping was then completed, and intraoperative indocyanine green fluoroscopy demonstrated good distal flow through the aneurysmal segment. The patient gave informed consent for surgery and video recording. The institutional review board approval was deemed unnecessary.
