Purpose: To evaluate the efficacy of n-butyl-2-cyanoacrylate (n-BCA) versus ethylene vinyl alcohol copolymer (ONYX) for the embolization of cranial dural arteriovenous fistulas (DAVFs).

Methods: 52 consecutive patients with DAVFs of the skull base and calvarium were treated with liquid embolic agents from November 2003 to November 2008. These 52 patients had 54 lesions treated with arterial embolization followed by venous sinus embolization, surgery or radiosurgery as needed. Patients in whom initial angiographic occlusion was accomplished by embolization underwent follow-up angiography at 3 months to assess for durable occlusion. …
