Online ahead of print.ABSTRACTOBJECTIVE: Primary infected aortic aneurysms are life-threatening if not treated promptly, but still possess a high mortality rate following open repair. The goal of treatment is to prevent rupture and clear infection. An endovascular approach is accepted as a bridge to definitive open repair. Our study compares the outcomes of endovascular versus conventional open repair of infected aortic aneurysms.METHOD: A single-center retrospective review was conducted of data from January 2012 to December 2021. Patients were categorized into three cohorts according to aortic involvement: thoracic aortic aneurysm (TAA), thoracoabdominal aortic aneurysm (TAAA), and abdominal aortic aneurysm (AAA). The primary endpoint was survival rate and the assessment of any associated factors.RESULT: Ninety-nine patients presented with infected aortic aneurysms. Of the 56 patients who presented with infected TAA, 38 patients underwent thoracic endovascular aortic repair and 18 patients underwent open TAA repair. Forty patients presented with infected AAA, of which 21 patients underwent endovascular aortic repair and 19 patients underwent open repair. Three patients presented with infected TAAA and all underwent open repair. The mean age was 67 years (range 33-88); 74 patients (74.8%) were men and 71 patients (71.7%) had immune dysfunction. Mean follow-up time was 24 months in the endovascular repair...
