Therapeutic embolization of cavernous sinus dural arteriovenous fistulas via transvenous approach.

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.
