AIM The aim of the study is to determine whether presentation and outcomes of inflammatory abdominal aortic aneurysms (IAAA) have changed over the last five decades. METHODS Comparison of current outcomes (January 2001 to December 2007) with results of the earliest report from our unit in 1972. RESULTS In contemporary series, 421 patients underwent AAA repair; 38 (9%) were IAAA. In 58% patients, IAAA was an incidental finding, whereas 42% patients were symptomatic with abdominal or back pain. Of those, 32% were ruptured IAAA. Male-to-female ratio was 12:1. Thirty-day mortality was 13%; elective 11.5%; emergency 17%. Comparison with 1972 study showed no change in the incidence and gender predilection. Presentation as an incidental finding and rupture increased 4- and 2-folds, respectively. CONCLUSION The incidence and gender predilection of IAAA have remained unchanged. The 4-fold increase in the presentation as an incidental finding reflects current trends in patient evaluation.
