B, Superselective venogram of the left SOV lateral view demonstrates multiple catheter support system with a 6F angled Envoy guiding catheter in the proximal left facial vein, a 4F Tracker 38 catheter in the left angular vein, and an Echelon 10 microcatheter.

C, Postembolization with coils and Onyx angiogram of the left CCA shows complete occlusion of the fistula with no residual filling.
