Post-traumatic carotid-cavernous fistula

Any abnormal connection between the carotid artery system and the cavernous venous system is called a cavernous carotid fistula [1]. Cavernous carotid fistula may occur following trauma or spontaneously [2]. CCF is one of the rare complications that may occur after head trauma. Although it is rare, it is very important and significant. CCF is reported to occur in 0.2% of patients with cranial trauma [3]. CCF is divided into direct and indirect types according to the place where the fistula separates from the carotid artery.
