Objective To investigate the feasibility ami safety of stenting in patients with subtotal occlusion of internal carotid artery. Methods The clinical data of 6 patients diagnosed as subtotal eniliolization with carotid artery stenting in Xuanwu Hospital, Capital Medical University from Decemlwr 2014 to July 2016 were analyzed retrospec tively. Results All 6 patients received carotid artery stenting. The stenosis rate was reduced from 95%-99% before procedure to 0-20% after procedure. The proximal protection device MO. MA was used during the operatinn. One patient had transient ischemic attack during the operation. Head MHI revealed that 1 patient had new cerebral infarction after procedure. All patients did not have any clinical symptoms of neurological defect after procedure. One patient had mild restenosis (rate of stenosis <50% ) in the 3-month follow-up observation. Conclusions Stenting for patients with subtotal occlusion of carotid artery is technically safe and feasible. The use of proximal protection device may contribute to the prevention of intraoperative emliolic events.
