In general, CS-DAVFs are treated with TVE through the IPS. However, in the present case, IPS was not used for the approach based on the angiographic appearance. Large drainage volume of the right facial vein enabled us to advance the guiding catheter to the angular vein with facility, and to pass the microcatheter system through the tortuous vessel with sufficient support of the guiding catheter. Cashmere, which is a 14 system infinity loop-shaped coil and relatively soft as a framing coil, had a tendency to attach to the anterior part of the CS wall.Because of good packing efficiency, transvenous Micrus coil embolization through the facial vein is an efficient treatment of DAVF involving the anterior part of the CS.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
