Dissection of Extracranial Internal Carotid Artery Due to Balloon Guiding Catheter Resulting in Asymptomatic Internal Carotid Artery Occlusion

Abstract

Dissection of the internal carotid artery (ICA) is a rare condition that accounts for a significant proportion of ischemic strokes in young adults. Iatrogenic dissection as a complication of neurointerventional procedures is a traumatic dissection which has been reported relatively rare in the literature. In this report, a case of dissection of the ICA is reported that was caused by repetitive movement of the balloon guiding catheter during stent-assisted thrombectomy (SAT), resulting in occlusion of the ICA.
