Balloon Occlusion of CC Fistula
A communication between the carotid artery and the cavernous sinus is a caroticocavernous sinus fistula (CC fistula). This could either be due to a dural arteriovenous malformation or be due to trauma. The treatment is to put an inflatable balloon into the fistula and thereby occlude the abnormal communication. The treatment is done by an interventional neuroradiologist.
