A 10-Year Retrospective Comparison of Endovascular and Open Aneurysm Repair for Infective Native Abdominal Aortic Aneurysm.

Background: This study compared outcomes of endovascular (EVAR) and open aneurysm repair (OAR) in patients with infective native abdominal aortic aneurysms (INAAAs), evaluating perioperative and in-hospital mortality, antibiotic treatment duration, complications, overall survival rates, and reintervention-free times at 10 years.

Methods: A retrospective cohort study of 125 INAAA patients (80 EVAR, 45 OAR) diagnosed between January 2004 and December 2019 was conducted. Patients were categorized as fit or unfit for open surgery based on cardiac, respiratory, and renal status, following the guidelines established in the EVAR-1 and EVAR-2 trials.
