title: Transarterial embolization of dural arteriovenous fistulas of the anterior cranial fossa with Onyx.
abstract: Dural arteriovenous fistulas (DAVF) of the anterior cranial fossa are often associated with hemorrhage and are usually treated surgically. This clinical study summarizes our preliminary experience in the transarterial embolization of these lesions. We retrospectively reviewed the data for 11 patients with anterior cranial fossa DAVF who underwent transarterial embolization with the Onyx Liquid Embolic System (eV3 Endovascular, Plymouth, MN, USA) at our institute between 2007 and 2011. In four patients, a balloon-assisted technique was used to facilitate superselective catheterization. According to the Cognard classification of DAVF, three fistulas were type III, and the other eight were type IV. DAVF were completely obliterated in 10 patients after treatment via a single ethmoidal artery, but the other patient was not completely cured. No signs of rebleeding or symptom progression were observed at a mean follow-up of 18.5 months (range: 2-49 months). Transarterial embolization using Onyx is therefore feasible and effective for the management of DAVF of the anterior cranial fossa.
