Fig. 1. A, Pre-embolization right CCA. Frontal projection arterial phase shows the dural CCF with early venous drainage into the left cavernous sinus followed by the left IPS.
B, Lateral projection of right CCA injection late capillary phase shows retrograde filling of abnormally dilated left SOV.
C, Unsubtracted lateral projection image demonstrates transjugular-IPS venous access to the left SOV and deployed coils in the left SOV.
D, Lateral view of the right CCA injection shows the repositioned microcatheter to the anterior compartment of the cavernous sinus and partial embolization with Onyx.
E and F, Postembolization CCA angiogram. Frontal projection (E) and lateral projection (F) demonstrate complete obliteration of the fistula. Deployed coils in the left SOV and Onyx cast in the left cavernous and coronary sinuses block the fistula. There is no residual fistula.
