From: Bilateral carotid cavernous fistula after trauma: a case report and literature review
A Catheter is inserted through the left femoral artery, and the balloon is placed at the fistula of the carotid cavernous sinus, showing that the balloon is completely herniated into the fistula. B Left carotid artery angiography shows the occlusion of the left internal carotid artery and that the fistula is completely closed. C Left vertebral artery angiography shows no countercurrent blood flow (white arrow) through the left posterior communicating artery and cavernous sinus fistula is completely blocked. D Right carotid artery angiography shows that the drainage veins of right superior ophthalmic vein and inferior petrosal sinus disappears after embolization of fistula with microcoil and Onyx glue
