Ruptured abdominal aortic aneurysms due to Salmonella, not of typhi species.

Ruptured aortic aneurysms due to Salmonella not of typhi species are rare and associated with high morbidity and mortality. We present three patients with Salmonella-infected ruptured aortic aneurysms successfully treated with an in situ prosthetic bypass graft. One patient had a saccular aneurysm at the infrarenal aorta and two patients had fusiform aneurysms at the aortic bifurcation. All the patients were treated with wide debridement of the infected aortic tissue followed by in situ graft replacement and long-term systemic antibiotic therapy. The method of revascularization, in situ bypass or extraanatomic bypass, remains controversial. On the basis of our clinical experience and recent literature focusing on more than 10 cases, in situ bypass reconstruction may be a feasible surgical technique for Salmonella-infected ruptured aortic aneurysm.
