Primary aortoduodenal fistula caused by Salmonella aortitis

Abstract

We report the management and follow-up of two cases of primary aortoduodenal fistulas caused by Salmonella aortitis. The origin, presentation, diagnosis, and results of operative therapy for patients with primary aortoduodenal fistulas, especially patients with positive aortic wall cultures, are reviewed. Successful therapeutic principles included early intervention, primary duodenal repair, aneurysm resection, aortic reconstruction with an in situ Dacron graft, and prolonged courses of bactericidal antibiotics.

Infected Aneurysm

“…Rupture into the vena cava (aortocaval fistula) is a less common presentation (4%). 11,20,28,29) plaque.…”

Adjacent Organ Involvement in Salmonella Aortic Aneurysms

“…aortoenteric fistulae (4,5). Such concomitant organ involvement has been reported only in isolated case reports (4,5). This study reports on 2 cases of fatal salmonella aortitis with unique adjacent organ involvement and gives a brief review of the literature.…”

“…Organs adjacent to aneurysms can also be affected through different mechanisms, such as by direct involvement through leakage as in empyema or via fistula formation, e.g. aortoenteric fistulae (4,5). Such concomitant organ involvement has been reported only in isolated case reports (4,5).…”
