Inflammatory aortic aneurysms (IAAs) represent a rare form of aortic aneurysms. Compared with atherosclerotic aneurysms, patients with IAA have an increased risk of perioperative and long-term morbidity. This retrospective clinical study analyzed the outcome after conventional and endovascular repair of IAAs. Patients treated for an abdominal IAA between January 1995 and November 2004 were included. Imaging (computed tomographic angiography or magnetic resonance angiography) was performed preoperatively and at the time of follow-up (mean 2.7 years). Transperitoneal open repair and endovascular aortic repair were the operative procedures used. Over 10 years, 40 patients were treated with conventional and 5 patients with endovascular repair. The in-hospital morbidity rate was 11.1% (five patients; four conventional, one endovascular). On 10 patients (47.6%), the retroperitoneal fibrosis was no longer detectable. After operative repair, the majority of cases presented with a distinct regression of inflammation. Endovascular treatment of IAA represents a feasible alternative procedure to open aortic repair.
