We report a case of traumatic carotid-cavernous fistula (CCF) that recurred some 9 years after carotid trapping. The recurrent CCF was accompanied by a huge aneurysmal dilatation of the cavernous sinus. Transarterial balloon occlusion of the proximal internal carotid artery failed to occlude the fistula completely because of collateral flow to the fistula. the fistula was completely occluded by a transvenous approach via the jugular vein and inferior petrosal sinus using detachable balloons. The transjugular-inferior petrosal approach to the cavernous sinus can be an alternative for the treatment of traumatic CCF when the transarterial approach has failed to occlude the cavernous sinus.
