title: Transvenous embolization for dural arteriovenous shunt of the cavernous sinus. Comparison of multi-staged transvenous embolization and transvenous embolization with sinus packing.
abstract: We describe the treatment and follow-up clinical symptoms and angiographic results in patients with dural arteriovenous fistula of the cavernous sinus treated by transvenous embolization (TVE). We have treated eight cases of dural arteriovenous fistula of the cavernous sinus by multi-staged TVE in two cases and TVE with sinus packing in six and three of six cases were treated with a combination of transarterial embolization. Multi-staged TVE was performed by occlusion from dangerous drainage veins to the cavernous sinus on several occasions. Angiographical results showed disappearance or reduction of the arteriovenous shunt in all cases. Six patients presented with ophthalmic symptoms and two had tinnitus. Six cases had complete disappearance of clinical symptoms after treatment. There was a deterioration of ocular movement in one patient treated by TVE with sinus packing. Multi-staged TVE was performed to reduce the coil volume for the packing of the cavernous sinus in two cases without cranial nerve palsy. Embolization, especially multi-staged TVE, was considered a good treatment to occlude arteriovenous shunts at the cavernous sinus without cranial nerve complications.
