Key words: dural arteriovenous fistulae; Onyx embolization

Intracranial dural arteriovenous fistulae (DAVF) with retrograde cortical venous drainage are uncommon lesions frequently associated with a poor prognosis if left untreated. The treatment of DAVFs with cortical venous drainage by endovascular occlusion of the entire arterial supply or the venous drainage is considered curative. We present our first endovascular experience with use of Onyx via the arterial route in these aggressive fistulas.
