Ruptured anterior communicating artery aneurysm associated with anterior cranial fossa dural arteriovenous fistula--case report.Neurol Med Chir (Tokyo). 2011; 51(1):40-4.NM
A 77-year-old man presented with an extremely rare association of anterior cranial fossa dural arteriovenous fistula (AVF) with anterior communicating artery (ACoA) aneurysm manifesting as consciousness deterioration due to intracerebral hemorrhage in the left frontal lobe and diffuse subarachnoid hemorrhage. Angiography confirmed the association of a dural AVF fed by both ethmoidal arteries and an ACoA aneurysm. Surgery for these two lesions was performed concurrently, and the ACoA aneurysm was found to be responsible for the hemorrhage. This association seems incidental, but is clinically significant since the preoperative determination of the bleeding point is difficult. We conclude that these two lesions should be treated simultaneously, to avoid leaving the ruptured point untreated.
