Transvenous embolization of an intraorbital arteriovenous fistula using Onyx

Abstract : We report a 61-year-old male with an intraorbital arteriovenous fistula. Due to the close proximity of the arterial feeder to the central retinal artery, and the tiny calibre of the draining branches of the superior ophthalmic vein, transvenous embolization of the fistula by Onyx was preferred. The procedure completely obliterated the shunt and the patient had complete relief of symptoms within 6 months.
