Abstract:
Objective To evaluate the results of thoracic endovascular aortic repair (TEVAR) for chronic type B aortic dissection.Methods From September 2005 to January 2013,30 patients with chronic type B aortic dissection received TEVAR.All patients were followed for 2-90 months [mean (33 ±25) months].Results All of the procedures finally achieved technical success.However,during TEVAR,there were transient endoleaks in 8 patients including type Ⅰ endoleaks in 3 patients,type Ⅱ endoleaks in 5 patients and persistent endoleaks in 3 patients which are type Ⅳ endoleaks.Type Ⅰ and type Ⅱ endoleaks were successfully managed during the procedures.There was no mortality or major complication during the perioperative period.Three patients died during follow-up:one patient died of carcinoma of the colon and two patients died of the complications of secondary interventions related to aortic dissection.Totally there were seven patients receiving secondary interventions.The Kaplan Meier actuarial survival curve showed a 5-year survival rate of 87.9％ and the 5-year survival rate without secondary intervention was 72.8％.Conclusions Early and midterm results showed that TEVAR was effective in treating chronic type B aortic dissection.
