Background/Objectives: Since thoracic endovascular aortic repair (TEVAR) and endovascular aneurysm repair (EVAR) are increasingly utilized, examining their outcomes and safety in real-world scenarios is crucial. This study investigated the management and outcomes of TEVAR and EVAR as alternatives to traditional open surgical repair for managing aortic pathologies. Methods: This was a retrospective cohort study. We analyzed the data from 59 consecutive patients who underwent TEVAR or EVAR between 2015 and 2022 at a single tertiary care center. The primary outcome was survival, and secondary outcomes were complications assessment, including re-intervention and occurrence of endoleaks. Results: TEVAR accounted for 47.5% of cases (n = 28), while EVAR comprised 52.5% (n = 31). Patients were mostly 61-70 years old (23.7%) and male (91.5%). Surgery indications differed, with aneurysmal repair being the prevalent indication for EVAR (90.3%, n = 28) and trauma being the main indication for TEVAR (67.9%, n = 19). Regarding the primary outcome, 11 patients (18.6%) died for various reasons; of those, 2 patients (3.4%) were determined to have died from vascular-related issues. Most patients (81.4%, n = 48) did not experience intraoperative complications. The most common intraoperative complications were endoleaks and access failure, each affecting 5.1% (n = 3) of patients. Re-intervention was necessary in 16.9% (n = 10) of cases, with endoleaks being the major indication (60%). Emergency intervention was more frequent in the TEVAR group (p = 0.013), resulting in significantly longer hospitalization (p = 0.012). Conclusions: Despite limitations, our analysis indicates a good safety profile with high success rates and a low incidence of adverse health outcomes and mortality in TEVAR/EVAR procedures. Nevertheless, the results emphasize the ongoing concern of endograft leaks, necessitating re-interventions.
