title: Percutaneous Transvenous Embolization of Intracranial Dural Arteriovenous Fistulas with Detachable Coils and/or in Combination with Onyx.
abstract: This study evaluated angiographic and clinical results in patients with a dural arteriovenous fistula (DAVF) who underwent percutaneous transvenous embolization. Retrospective chart analysis and radiographic studies were performed in 23 patients (aged 11-70 yrs) with a DAVF treated with percutaneous transvenous embolization in the past five years. Lesions were located in the anterior cranial fossa, cerebellar tentorium, transverse-sigmoid sinus and cavernous sinus. All procedures were analyzed with regard to presentation, delivery, angiographical and clinical outcome. Data for 23 patients (age range, 11-70 yrs, mean age 49.5yrs) with DAVFs (cavernous sinus[ CS], n=17; transverse-sigmoid sinus, n=3; anterior cranial fossa, n=2; cerebellar tentorium, n=1) were retrospectively reviewed. The DAVFs were treated with coils or a combination with Onyx via different transvenous approaches, in 28 procedures. Cerebral angiography was performed to confirm the treatment. The mean clinical follow-up period was 22.1 months. Transvenous treatment of intracranial DAVFs can be safe and effective if various transvenous approaches are attempted. Percutaneous transvenous embolization with detachable platinum coils or a combination with Onyx is effective in the treatment of DAVFs.
