Objective:To evaluate the safety and efficiency of transvenous embolization of dural arteri-ovenous fistula of cavernous region by multiple venous routes. Methods: Twenty seven patients with dural arteriovenous fistula of cavernous region were treated by transvenous embolization with micro-coils. The transvenous routes included inferior petrosal sinus, superior ophthalmic vein and facial vein. Results: Clinical cure was achieved in 23 cases and significant improvement of symptoms in 4 cases. Complete angio-graphic obliteration was documented in 22 patients (82%). Residual shunting were left in 2 patients via pterygoid drainage and 1 case via inter-cavernous sinus, 2 cases via inferior petrosal sinus, disappeared one month later by manual compression carotid artery. Headache and vomiting were the most common symptoms after embolization. Three patients had diplopia and relieved within two months after embolization. There was no permanent procedure-related morbidity. The clinic follow up ranged from 5 months to 6 years, and there was not recurrence case. Conclusion: Transvenous embolization via different venous routes is a safe and efficient method for dural arteriovenous fistula of cavernous region treatment.
