BACKGROUND: There is no standard treatment for patients with infected abdominal aortic aneurysm (AAA). To determine the basis for selection of a surgical method, we reviewed our experiences with all patients who underwent surgery for infected infrarenal AAA.
METHODS: Between 1993 and 2000, 6 patients with infected infrarenal AAA underwent surgery. Extra-anatomic bypass grafting was performed in 2 of 3 patients with infection extending into the retroperitoneum. In situ grafting was performed in 3 patients with localized infection and in 1 patient with extended infection.
RESULTS: Severe peritonitis occurred in 2 patients with extended infection in the early postoperative phase. One patient, who had undergone in situ grafting, died of sepsis. The other patient, who had undergone extra-anatomic bypass grafting, was treated by continuous irrigation with an electrolyzed strong acid aqueous solution (ESAAS). He recovered gradually and was discharged. After a follow-up period with a mean of 40 months (range: 17-102 months), all 5 patients who survived surgery are alive and asymptomatic.
CONCLUSIONS: It was suggested that the method used for revascularization should be selected based on the degree of diffusion of infection. For a patient with extended infection, postoperative continuous irrigation with ESAAS appears to be effective in eradicating retroperitoneal infection.
