Abstract: Objective Investigate the effect of the fenestrated thoracic endovascular aortic repair(TEVAR) in the treatment of aortic arch disease.
Methods Clinical data of 57 patients with aortic arch lesions admitted to our hospital from April 2012 to January 2017 were retrospectively analyzed.All patients were treated with fenestrated TEVAR technology,and the efficacy was observed by immediate postoperative internal leakage,stent displacement,cerebral infarction,branch vascular patency rate,secondary intervention and survival outcome.
Results (1)Perioperative conditions: clinical surgical success rate 96.5% (55/57),intraoperative complications were 10.53% (6/57),2 cases of fenestration position offset emergency to chimney,2 cases of  model of leakage,2 cases of Ⅲ type of leakage,3 cases of postoperative leakage within 30 day review intraoperative disappeared,no new deaths.New stent related complication rate 3.51% (2/57),including acute cerebral infarction,Ⅲ leakage in 1 case,Ⅲ leakage in the secondary surgery in 1 case.(2) survival outcome: the follow-up period was 3～36 months,and the follow-up rate was 92.98%(53/57).New stent related complication rate 5.26% (3/57),acute cerebral infarction,left common carotid artery occlusion,Ⅲ type of leakage in 1 case.Two cases of secondary surgical intervention.There were 3 deaths.The 3-year survival rate was 89.47% (51/57).
Conclusion The application of fenestrated TEVAR technique in the treatment of aortic arch disease is safe and effective.
