Postoperative Dural Arteriovenous Fistula after Clipping of Ruptured Saccular Aneurysm of Pericallosal Artery

Abstract

Dural arteriovenous fistulas (DAVFs) are pathologic dural shunts characterized by meningeal arterial supply, absence of nidus and drainage to dural venous sinuses or cortical veins. They are usually acquired lesions associated with specific disease and inflammatory processes, including craniotomy. We report a case of postoperative DAVF in a 59 year-old male presenting with a ruptured distal right anterior cerebral artery aneurysm. After an uneventful microsurgery for clipping, meningitis occurred on the ninth day, and was successfully treated. The one-year control angiogram showed a left occipital DAVF. The relevant literature on the occurrence of DAVFs is also presented.
