[Embolization of carotid-cavernous fistulas by retrograde catheterization via superior ophthalmic vein]

Six patients with traumatic carotid-cavernous fistula (CCF), which was failed to the standard endoarterial embolization for various reasons, were successfully cured by retrograde catheterization via the superior ophthalmic vein (SOV). The well dilated SOV was easily exposured (4 cases) or punctured (2 cases). Catheterization was performed under X-ray monitoring and reached into the cavernous sinus. Detachable balloon was used in 4 and IBCA glue in 2 cases for embolization. There were no intra or post-operative complication. All the symptoms and signs were disappeared in all the 6 cases after treatment. The authors suggest that in some CCF cases the SOV route is a promising approach.
