AbstractInflammatory abdominal aortic aneurysm (IAAA) is characterised by thick aortic wall, with perianeurysmal fibrosis extending to adjacent organs. This study aimed to determine the early surgical outcomes of 10 IAAAs and compare the risk factors, perioperative complications, and 30-day mortality of these patients to 50 degenerative AAAs (dAAA), who underwent open repair in Sina Hospital, Tehran, Iran. The study was conducted from 2011 to 2019. IAAA patients were followed for 22.7 ± 3.8 months. The frequency of IAAA was 4.9%. All IAAA patients were males and smokers. There was no statistical difference in preoperative risk factors (age, smoking, hypertension, chronic kidney disease, ischemic heart disease, chronic obstructive pulmonary disease), operation time, blood loss, postoperative complications between dAAA and IAAA patients. The thirty-day mortality rate of open surgeries in degenerative and inflammatory cases was 8% (N=4) and 10% (N=1), respectively. Open repair with proximal/and/or distal clamping, avoids severe adhesiolysis, procedure-related morbidity, and 30-day perioperative mortality. Key Words: Inflammatory abdominal aortic aneurysm, Open surgery, Mortality, Outcome, Degenerative aortic aneurysm.
