Combined transarterial N-butyl cyanoacrylate and coil embolization of direct carotid-cavernous fistulas. Report of two cases.

The authors report two cases of traumatic carotid-cavernous fistulas treated successfully with combined N-butyl cyanoacrylate glue and coil embolization via a transarterial approach. In both cases complete occlusion of the fistula was achieved, with preservation of the parent carotid artery. Casting of the cavernous sinus with a liquid embolic agent was well tolerated and produced no complications of cranial nerve palsy. This technique provides interventionalists with yet another treatment option in these often complex cases.
