The aim of our study was to compare early and long-term results of open repair of patients with inflammatory abdominal aortic aneurysm (IAAA) with matched cohort of patients with abdominal aortic aneurysm (AAA). This retrospective single-center cohort study used prospectively collected data from an institutional registry from 1786 patients between 2009 and 2015. Patients with IAAA and AAA were matched by propensity score analysis controlling for demographics, baseline comorbidities, and AAA parameters in a 1:2 ratio. Patients were followed for 5 years. There were 76 patients with IAAA and 152 patients with AAA. Open repair of IAAA is challenging and comparing to AAA carries a higher perioperative risk and long-term infection rate, even in high-volume centers. The main causes of complications are intraoperative injury of adjacent organs, bleeding, and coronary events. Patients with AAA in a matched cohort showed equal long-term survival, which should be assessed in bigger registries.
