A Case of Dural Arteriovenous Fistula with Multitudinous Feeders Treated by Transvenous Embolization / 대한이비인후과학회지

ABSTRACT

Dural arteriovenous fistula (DAVF) is an uncommon condition. However, it is important for otologists because it is the most common cause of pulsatile tinnitus and may also present with intracranial hemorrhage and neurological disturbance. Many therapeutic approaches, such as surgery and endovascular techniques, have been proposed to obliterate the lesions. Surgery may be accompanied by massive blood loss. Transarterial embolization seldom obliterates transverse-sigmoid sinus DAVFs completely and permanently. In recent years, several authors have reported the effect of transvenous embolization of transverse-sigmoid sinus DAVFs in English literature. We recently experienced a case of sigmoid DAVF treated by transvenous embolization and report it with a review of the literature.
