Spontaneous Occlusion of Traumatic Carotid Cavernous Fistula with Pseudoaneurysm Formation-management with Neuroform Stent and Coiling: A Case Report

Abstract

We experienced a case of traumatic carotid cavernous fistula (CCF) which was occluded spontaneously within 7 days after transfemoral carotid angiography with complete disapperance of symtoms. Traumatic CCF is almost always type A and known to rarely resolves spontaneously. The suggested mechanism of spontaneous occlusion were manual compression of carotid artery, hypotension during percutaneous or open direct carotid angiography under general anesthesia in the past as well as thrombogenicity of iodinated contrast media and catheterization procedure itself are more related with recent transfemoral carotid angiography. The pseudoaneurysm managed with coil or balloon should be frequently followed up due to compaction by the surrounding thrombus.
