Objective: Craniocervical junction arteriovenous fistula (CCJ-AVF) is a very rare vascular malformation, and its pathophysiology, natural course, and optimal treatment strategy have not been clearly elucidated. We report a case of CCJ-AVF that occurred with subarachnoid hemorrhage and was completely treated by transarterial embolization.
Case Presentation: A 61-year-old-man presented with severe subarachnoid hemorrhage. Cerebral angiography showed a CCJ-AVF and a small aneurysm on the feeder from the anterior spinal artery, which was the origin of the hemorrhage. The fistula and the feeder aneurysm were occluded completely by transarterial embolization with n-butyl cyanoacrylate (NBCA).
Conclusion: The arteriovenous system around the CCJ is extremely complicated, necessitating a thorough understanding of the detailed vascular anatomy of CCJ and precise interpretation of angiographic findings before determination of the treatment strategy.
