Thoracic Endovascular Aortic Repair in 300 Patients: Long-Term Results

Background. The aim of this analysis was to assess short and mid-term results of patients undergoing thoracic endovascular aortic repair (TEVAR) for 4 different indications. Methods. From 1996 to 2010, 300 patients (80 female, 220 male, median age 67 years [20 to 88]) underwent TEVAR at our department. Among them were 137 descending thoracic aneurysms (DTA), 80 type B dissections (60 acute, 20 chronic), 59 perforating aortic ulcer (PAU), and 24 traumatic aortic transections (ATAT). Hospital mortality and mid-term survival among different indications for TEVAR were evaluated. Results. Overall hospital mortality in our series was 5% (n [15). Seven patients with DTA (5%), 4 patients with type B dissections (5%), 2 patients with PAU (3.4%), and 2 ATAT (8%) patients died during their hospital stay. Kaplan-Meier survival analysis revealed significant differences in survival rates according to the various indications for TEVAR (p < 0.001). Overall long-term mortality was 86%, 63%, and 44% at 1, 5, and 10 years. Early and late endoleak rate was 18% and 8%, respectively. Conclusions. The TEVAR has evolved into a safe and effective therapy for different aortic pathology resulting in promising long- term results. Nevertheless, the indication for TEVAR has direct impact on the success of the procedure. Patients with acute type B aortic dissections and acute traumatic aortic lesions seem to benefit the most from TEVAR.
