Traumatic Carotid-cavernous Fistula with Unilateral Double Fistula ・ A Case Report

Abstract

A rare case of traumatic carotid-cavernous fistula (CCF) with unilateral double fistula in a 67-year-old male is presented. An angiogram demonstrated double arterio-venous fistula in the dorsomedial wall of C4 and the ventrolateral wall of C5 of the left internal carotid artery. Both fistulae were successfully obliterated with detachable balloon and platinum coils. Direct laceration of the different segment of the internal carotid artery was a possible cause of the double arterio-venous fistula. The mechanisms for formation of double arterio-venous fistula were discussed.
