Objective: We report a rare case of pterygopalatine fossa arterial venous shunt disease with venous congestion of the superior ophthalmic vein (SOV) that was treated by transarterial balloon-assisted embolization.
Case Presentation: A 57-year-old man presented with congestion of the right bulbar conjunctiva, protrusion, and swelling of the right eyelid was admitted to our hospital. Angiography demonstrated an arteriovenous fistula (AVF) forming small congregated vessels in the pterygopalatine fossa fed by the branch of the ophthalmic artery (OA) and artery of the superior orbital fissure, draining into the SOV via the inferior ophthalmic vein (IOV). From the artery of the superior orbital fissure, transarterial embolization (TAE) with ONYX using a dual-lumen balloon catheter was performed. The patient was treated without complications.
Conclusion: TAE using transarterial balloon-assisted embolization with ONYX is effective for periorbital arteriovenous shunts, although special care is necessary to prevent the migration of ONYX into the OA.
