Cavernous Dural Arteriovenous Fistula (AVF): Angio-CT-Guided Fistula Site Localization
A 34-year-old male presented with left eye conjunctival congestion and proptosis. MRI (not shown) revealed dilated left superior ophthalmic vein as well as prominence of left cavernous sinus. Cerebral DSA was performed which showed left cavernous sinus dural AVF with feeders from left internal and external carotid arteries (Fig. 60.1a–c). The AVF was draining via left ophthalmic vein into the left facial vein (Fig. 60.1c). No obvious drainage into the petrosal system was observed. Transvenous embolization with detachable coils was planned.
