RESUMO
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.

Dural carotid-cavernous fistula (CCF) is characterized by arteriovenous communications between the meningeal branches of the internal or external carotid arteries and the cavernous sinus. Although the triad of chemosis, proptosis, and ocular bruit has been regarded as a classic sign of CCF, dural CCF often lacks these features. Dural CCF is a rare cause of ophthalmoplegia, and so it may be overlooked when the classic symptoms are absent. We report herein a case of bilateral dural CCF that presented as unilateral isolated abducens nerve palsy.
