A Case of Cavernous Sinus Dural Arteriovenous Fistula Which Required Another Embolization of Contralateral Cavernous Sinus Just after Embolization

Abstract

Objective: We report a case of cavernous sinus dural arteriovenous fistula (CS-DAVF) in which another feeder in the other compartment became apparent just after selective transvenous embolization (TVE).

Case presentation: A 76-year-old woman complained of tinnitus and diplopia, proptosis, and conjunctival injection of right eye. Cerebral angiography showed CS-DAVF with fistulous points around right cavernous sinus (CS), posterior intercavernous sinus and left CS, draining to the right CS and right superior ophthalmic vein via basilar sinus. Although selective TVE including the affected left CS was performed via right inferior petrosal sinus, another feeder in the right CS became apparent just after embolization, and additional embolization was required.

Conclusion: It is important to recognize that another feeder in the other compartment may become apparent just after selective TVE of CS-DAVF.
