Abstract
Vertebral arteriovenous fistulas are rare clinical entities. Most cases are trauma-related or iatrogenic in origin. Treatment options include endovascular occlusion or direct surgical closure. We report a case of an iatrogenic vertebral arteriovenous fistula, diagnosed because of a neck bruit in a patient following a subarachnoid hemorrhage, successfully treated with electrodetachable coil and polyvinyl alcohol embolization. The use of electrodetachable coils may be an effective alternative for the endovascular occlusion of such relatively large fistulas. Furthermore, parent artery occlusion by endovascular embolization seems to be an effective and safe procedure, especially when the ipsilateral posterior inferior cerebellar artery was positioned distal to the fistula and was fully supplied retrogradely by the contralateral vertebral artery.
