Carotid stump is blind remnant of occluded proximal segment of the internal carotid artery (ICA) that can become the potential source of embolism. Carotid stump syndrome is a potentially treatable cause of recurrent ischemic events in the carotid territory in the setting of occlusion of the ipsilateral ICA. It is thought to be caused by turbulent blood flow in the patent stump of the occluded ICA causing microemboli migrating in the brain through external carotid-ophthalmic anastomotic channels and retrograde flow. Here, we report a patient with known ipsilateral chronic ICA occlusion, who was on best medical management, presented on two separate occasions with recurrent embolic infarctions in ipsilateral carotid territory. She was diagnosed with carotid stump syndrome and treated through endovascular route with clinical and angiographic follow-up.
颈动脉残端是颈内动脉（ICA）闭塞近端的盲端残余部分，可成为潜在的栓子来源。颈动脉残端综合征是同侧ICA闭塞情况下，颈动脉区域复发性缺血事件的一个潜在可治疗原因。其被认为是由于闭塞的ICA开放残端内的血流紊乱，导致微栓子通过颈外动脉-眼动脉吻合通道在脑内迁移以及逆行血流所致。在此，我们报告一名已知患有同侧慢性ICA闭塞的患者，该患者接受了最佳药物治疗，两次分别出现同侧颈动脉区域的复发性栓塞性梗死。她被诊断为颈动脉残端综合征，并通过血管内途径进行治疗，同时进行临床和血管造影随访。
