Mid- and long-term results in patients with thoracic endovascular aortic repair

Objectives: In this study, we aimed to examine the midand long-term results of the patients undergoing thoracic endovascular aortic repair (TEVAR) in our clinic. Patients and methods: Between June 2006 and October 2018, a total of 71 patients (59 males, 12 females; mean age: 60.9±13.3 years; range, 17 to 79 years) who underwent TEVAR electively or urgently were retrospectively analyzed. Data including demographic and clinical characteristics of the patients and operative data were recorded. Results: Of the patients, 22 (31%) were urgently operated and 49 (69%) were electively operated. Cerebrovascular disease (CVD) developed in three (4.2%) patients. Thirty-day overall survival of patients who were operated on emergency was found to be 72.7%, and this rate was 98% in elective patients (p=0.001). One-year overall survival of our patient series was 76.1%. One-year survival rate of emergency patients was 54.5%, and this rate was 85.7% in elective patients (p=0.002). Two-year overall survival of emergency patients was 45.5% and it was 79.6% in elective patients (p=0.002). While the survival rate of preoperative smokers after two years was 60.8%, it was calculated as 90% of preoperatively non-smokers (p=0.022). Conclusion: Thoracic endovascular aortic repair treatment seems to show similar results to open surgery in terms of mortality and other complications in the midand long-term. With the developing stent-graft technology, TEVAR results can be even better in the future.
