FIG 5. Case 9.
A, Left ECA angiogram in lateral view. There is convergence of feeders toward two points of the cavernous sinus (small arrows). Long arrow is showing a microcatheter into the cavernous sinus (through the inferior petrosal sinus).
B, Conventional radiograph, showing high-density cast of coils into the most anterior septation (arrow) and low-density cast in a portion of the cavernous sinus.
C, Left ECA angiogram in AP view after embolization, showing total occlusion of the DAVS.
D, Left ECA angiogram in lateral view 1 month after embolization, showing recurrence of the shunt only in the posterior septation (arrow). There is no more drainage toward the inferior petrosal sinus.
E, Conventional radiograph at the end of the second session of embolization. Large arrow show 5F guide catheter into the facial vein (transfemoral approach). Arrow shows fragments of NBCA injected in the accessory meningeal artery.
F, Left ECA injection in lateral view after embolization, showing complete occlusion of the DAVS.
