Transvenous Embolization of Dural Carotid Cavernous Fistula through the Supraorbital Vein.

We describe a case of transvenous embolization through the dilated supraorbital vein to treat a dural carotid cavernous fistula. The approach through the common facial vein or direct access of the superior ophthalmic vein is a commonly used route to the superior ophthalmic vein when the approach via the inferior petrosal sinus is unavailable. In rare cases, the dilated supraorbital vein provides an alternative route and we discuss the technical details.
