Transfemoral superior ophthalmic vein approach via the facial vein for the treatment of carotid-cavernous fistulas--two case reports

Two elderly female patients with carotid-cavernous fistulas (CCFs) were treated by transvenous embolization through a transfemoral superior ophthalmic vein approach via the facial vein. Complete occlusion of CCFs was not achieved with this technique exclusively, but the technique was effective in these cases. This technique provides an alternative to other transvenous approaches for the treatment of CCFs.
