Technical Pitfalls in the Endovascular Treatment of Traumatic Pseudoaneurysm of the Internal Carotid Artery: Case Report

  • 1Department of Neurological Surgery, Asan Medical Center, University of Ulsan College of Medicine, Seoul, Korea. jsahn@amc.seoul.kr


A posttraumatic pseudoaneurysm of the internal carotid artery (ICA) is a rare cause of massive epistaxis, and this can be fatal. Treating a ruptured traumatic pseudoaneurysm of the cavernous ICA is challenging as the treated patient has the same risk profile as an untreated patient if the procedure results in only incomplete occlusion. For this reason, additional procedures need to be performed for these cases. The present report describes two cases of a traumatic ICA pseudoaneurysm that was only partially occluded by endovascular balloon placement because an external carotid-ophthalmic artery anastomosis was not detected. The patients were immediately and successfully treated by performing surgical clipping of the ICA.
