Abstract：Objective To evaluate the safety of covering the left subclavian artery(LSA)in the endovas-cular repair of acute aortic dissection (TEVAR). Methods Retrospective analyses were conducted on 99 cases of acute aortic dissection in patients undergoing endovascular repair during January 2010 to June 2016 in our hospi-tal,in which cases,LSA without plugging were 53 cases,partial closure were 19 cases,blocking were 27 cases. Analysis and comparison the performance of stroke and the incidence of paraplegia between each group in perioper-ative period,and following up long-term postoperative of patients with left upper limb ischemia symptoms and the incidence of stroke. Results During the period of hospitalization all patients were free of left upper limb ischemic pain;3 cases(3%)occurred in TIA and a black haze after surgery,including 2 cases(2%)without plugging and 1 case(1%)of LSA blocking; none perioperative paraplegia. Mean follow-up were 37.7 months(2-73). The results were analyzed for statistical significance,which showed that LSA blocking may increase the incidence of stroke in mid-term follow-up,and upper limb blood pressure and left upper limb ischemia symptoms were different. Conclusion LSA Blocking in TEVAR does not increase stroke risk and paraplegia in perioperation period,may increase the long-term risk of stroke after operation. For alleviating the lack blood symptoms of left upper limb in long-term. It should to be scheduled for LSA revascularization.
