Purposes: To assess overall survival and to determine factors predicting outcome after thoracic endovascular aortic repair. Materials and methods: A Retrospective analysis was performed on a cohort of 212 consecutive patients (165 men and 47 women; mean age 64 years) who underwent thoracic endovascular aortic repair in a tertiary referral center for aortic disease. Main indications were true thoracic aortic aneurysm (n = 58; 27.6%), traumatic aortic rupture (n = 33; 15.7%), anastomotic pseudoaneurysms (n = 23; 10.9%), chronic type B aortic dissection (n = 22; 10.5%), and symptomatic, acute type B dissection (n = 21; 10.0%). In 79 patients (37.3%), a hybrid procedure, including supra-aortic rerouting, was performed. Kaplan–Meier estimates were used for overall survival and Cox regression models were used for univariable analysis of the association between risk factors and survival. Results: Proximal landing zones were predominantly zone 3 (n = 66; 31.3%), zone 2 (n = 63; 29.9%), and zone 1 (n = 38; 18%). In-hospital mortality was n = 18 (8.5%). Overall survival was 79.6%, 65.9%, and 51.1% at 2, 5, and 10 years, respectively; better overall survival was shown for traumatic aortic rupture, anastomotic pseudoaneurysms, and chronic posttraumatic pseudoaneurysms (p
