Inflammatory abdominal aortic aneurysms. A 20-year experience

Aim. The aim of the study was to report a 20-year single Institution experience, with the early and late outcomes of surgical treatment of inflammatory abdominal aortic aneurysms. Methods. In a 20-year period, 2 275 consecutive patients underwent elective surgical repair for non-rupture abdominal aortic aneurysm. Fifty-two patients (2.3%) were classified as inflammatory abdominal aortic aneurysms. Early and late outcomes were analyzed. Results. One patient died in the perioperative period, giving a mortality rate of 1.92%. One patient died from a pseudoaneurysm rupture 7 months after operation. Three patients developed an aortic pseudoaneurysm in the follow-up period (mean 12.1 years, range 1-20 years) and underwent a redo operation. Conclusion. Overall surgical outcome of these patients, in terms of short-term and long-term is good. A high rate of pseudoaneurysm formation was observed.
