Abstract：Objective To explore the safety and efficiency of selective coverage of the left subclavian artery (LSA) during thoracic endovascular aortic repair(TEVAR) with insufficient proximal landing zone.Methods All 73 patients underwent TEVAR in our hospital suffered intentional coverage of LSA.LSA was completely covered in 44 cases(group A) and partially covered in 29 cases (group B).Perioperative and follow-up mortality,neurologic complication,ischemia of the left upper limb,endoleak and secondary treatment were compared between two groups.Results All 77 stent-grafts were implanted for all patients with successful technique.Two stent-grafts were used for 4 patients while only one for each of the others.There was no statistical difference between group A and B regarding perioperative mortality,neurologic complication,serious ischemia of left upper limb,endoleak and secondary treatment.After follow-up of (28 ± 13) months,there were significant statistical differences between two groups only regarding ischemia and occlusion of left upper limb [37.8％ (14/37) vs 4.0％ (1/25),29.7％ (11/37) vs 0.0％ ; P ＜ 0.05].Conclusion Selective coverage of LSA ostium is safe and feasible for patients with insufficient landing zone during TEVAR,especially with partially coverage.Carefully preoperative analysis of the imaging is necessary.
