Abstract

Background: To review the outcome of infected aneurysms and pseudoaneurysms of the thoracic and abdominal aorta treated in a major teaching hospital.

Methods: Between December 1994 and January 2003, 13 infected aortic aneurysms and pseudoaneurysms (5 thoracic, 4 paravisceral, 4 infrarenal) in 10 consecutive patients were treated surgically. Aortic debridement with in situ reconstruction is our standard practice. Endovascular repair was offered to suitable patients with thoracic aortic involvement.

Results: There were six men and four women with a mean age of 63 years. The commonest pathogen was Salmonella species, accounting for 50% of the cases. Aortic debridement with in situ revascularization was performed for six patients with visceral reconstruction in four of them. One patient with aortic bifurcation involvement and gross purulent infection had ligation and debridement followed by right axillobifemoral bypass. Four infected thoracic aortic pseudoaneurysms in three other patients underwent endovascular repair. There was no hospital death, limb loss, renal failure, or intestinal ischemia. There were two late deaths from sepsis and pneumonia at 3 months and 77 months after operation. Eight patients were alive after a mean follow-up of 36 months and no late graft infection was evident.

Conclusions: Surgical treatment for infected aortic aneurysms with in situ reconstruction is associated with favorable outcome and good long-term result. Endovascular repair has a potential role.
