Transvenous embolization of cavernous sinus dural arteriovenous fistula using the direct superior ophthalmic vein approach: a case report.

Transvenous coil embolization has been successfully applied for the treatment of cavernous sinus dural arteriovenous fistula (CSDAVF). Unfortunately, the technique cannot be applied in cases of poor or absent inferior petrosal sinus or facial venous access route to the fistula. Recently, we experienced a successful embolization using direct superior ophthalmic vein approach in cases of CSDAVF which were no opacification of inferior petrosal sinus or facial vein.
