Abstract

Dural arteriovenous fistula (DAVF) is classically defined as abnormal arteriovenous connections between an arterial feeder and a dural venous sinus or leptomeningeal vein with the channels located within the dural leaflets [1]. Onyx is a non-adhesive liquid embolic agent and does not polymerize. The dimethyl sulfoxide can diffuse under aqueous conditions and occlude mechanically the feeders [2]. We describe transarterial embolization with dual-lumen balloon microcatheter with Onyx (Medtronic, Minneapolis, MN, USA) for dural arteriovenous fistula (DAVF) of sinus confluence.
