Cavernous Sinus Dural Arteriovenous Fistula (AVF): Trans-venous Approach Through Inferior Petrosal Sinus
A 48-year-old lady presented with proptosis and congestion of the right eye. MRI revealed enlarged right cavernous sinus along with dilated right ophthalmic vein. DSA showed a right cavernous sinus dural arteriovenous fistula draining through right ophthalmic vein. Feeders were from bilateral external and left internal carotid arteries (Fig. 59.1). Stenosis was seen in ophthalmic vein at its exit from orbit and was draining into multiple small venous channels. Right inferior petrosal sinus was not visualized. Case was planned for trans-venous coil embolization.
