Therapeutic embolization of cavernous sinus dural arteriovenous fistulas via transvenous approach
1Department of Neurosurgery, First Affiliated Hospital, Jilin University, Changchun 130021, China.
Objective:
To describe the transvenous catheterization technique for the treatment of cavernous sinus dural arteriovenous fistulas (CSdAVFs), including its indications, complications and efficacy.
Methods:
Eight patients with symptomatic CSdAVFs were treated by endovascular embolization with platinum coils, via the inferior petrosal sinus (IPS) in 6 patients, and via the Sylvian vein after surgical exposure in other 2 patients.
Results:
Complete angiographic resolution of the fistula was obtained in six patients immediately after the procedures, and a complete resolution of symptoms and signs was achieved in all patients. The residual fistulas in two patients disappeared completely in the follow-up angiography.
Conclusion:
Transvenous embolization is a useful and safe approach in the management of CSdAVFs.
