Objectives: To review our surgical experience of primary infected abdominal aortic aneurysms, with the aim of assessing the safety and durability of in situ prosthetic replacement. Design: Retrospective study in a university hospital. Materials and Methods: Thirty-four patients who underwent surgery for primary infected abdominal aortic aneurysms over the past 18 years were reviewed. Operative details and outcomes were recorded for analysis. Results: There were six suprarenal and 28 infrarenal infections. Salmonellae (18 patients) were the most common pathogens. Thirty patients underwent in situ prosthetic replacement, two underwent extra-anatomic bypass and two underwent endovascular repair. The surgical mortality for overall patients was 18%, and for patients reconstructed in situ, 17%. Among the 30 patients reconstructed in situ, four patients who underwent concomitant gastrointestinal procedures (e.g., repair of the duodenal defect) died. By contrast, 25 of 26 patients without gastrointestinal involvement survived surgery. After a median follow-up period of 58 months, two discharged patients who underwent in situ reconstruction died of late graft infection. Conclusions: Our experience suggests that in situ prosthetic replacement can be performed safely with durable outcomes in the majority of patients with infected abdominal aortic aneurysms. Nevertheless, we advise caution when considering this technique with concomitant gastrointestinal procedures.
