Embolization of cerebral dural arteriovenous fistula of the cavernous sinus through the superior ophthalmic vein approach

Objective To evaluate the clinical effect of embolization of cerebral dural atreriovenous fistulas (cDAVF) of the eavemous sinus through the superior ophthalmic vein approach. Methods Twnety-seven patients with eDAVF of the cavernous sinus were embolized through the superior ophthalmic vein approach. Cerebral angiography and follow-up examination of the patients were performed to evaluate the effect ofernbolization. Results The fistulae showed complete angiographic disappearance in 15 patients, and 12 patients had blood velocity flow reduction at the fistula orifice. Ocular proptosis and chemosis deteriorated transiently in 11 patients after the procedure. The patients were followed-op for 3 to 48 months, and clinical cure was achieved in 17 patients, and 10 showed significant symptom relief. Conclusion cDAVF of the cavernous sinus can be effectively embolized through the superior ophthalmic vein approach.
