dissection of extracranial internal carotid artery due to balloon guiding catheter resulting in asymptomatic internal carotid artery occlusion

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.
