INTRODUCTION: Studies on the mid and long-term outcomes of thoracic endovascular aortic repair (TEVAR) are scarce. This study aimed to investigate the long-term outcomes of TEVAR for all-comers patients with various types of thoracic aortic pathologies, predominantly thoracic aortic dissections and thoracic aortic aneurysms.
METHODS: Between January 2005 and December 2015, 123 consecutive patients with thoracic aortic pathologies underwent TEVAR. The patients were divided into groups based on aortic pathologies (dissections or aneurysms) and the type of procedure (hybrid TEVAR or non-hybrid TEVAR). Mortality, complications, and reintervention rates were compared between these four groups. The Kaplan-Meier curve and the Cox regression analysis were employed to estimate survivals and factors associated with 5-year mortality.
RESULTS: One hundred twenty-three consecutive patients with various aortic pathologies undergoing TEVAR were evaluated. Hypertension (79.7 %) and smoking (39 %) were the most common comorbidities in the study population. The patients were followed up for a mean duration of 58.1 ± 7.1 months to evaluate the postprocedural surveillance. Most complications occurred in the dissection and hybrid groups; however, these differences were nonsignificant. The overall 5-year surveillance and reintervention rates were 65 % and 12.1 %, respectively. A significant difference existed in 5-year survival between the patients with aneurysmal and aortic dissection pathologies based on the log-rank test (P = 0.01). On the other hand, no significant differences were observed in 5-year survival between the patients who underwent hybrid and non-hybrid TEVAR. The Cox regression analysis confirmed that chronic kidney disease, previous coronary artery bypass grafting, age >65 years, platelet counts <150∗ 103/μL, aneurysmal aortic pathology, and ejection fraction ≤ 50 % were predictors of 5-year mortality.
CONCLUSIONS: The long-term outcomes of TEVAR for various aortic pathologies disclosed that this procedure was well-tolerated in a group of patients with high comorbid conditions. The five-year survival rate of TEVAR for thoracic aortic dissections was more favorable than that for thoracic aortic aneurysms, but there were no significant differences between hybrid and non-hybrid procedures regarding the mortality rate.
