Subarachnoid hemorrhage due to rupture of infundibular dilation of a circumflex branch of the posterior cerebral artery: case report.
The authors describe a rare case in which an infundibular dilation at the origin of a circumflex branch of the P1 segment of the posterior cerebral artery caused subarachnoid hemorrhage. Wrapping was performed by a subtemporal approach in the delayed stage. At the time of surgery, the rupture point was found in the infundibular dilation.
