Ruptured Mycotic Salmonella Aortic Aneurysm Treated with Combined Cefotaxime Antibiotic and Staged Surgical Management

Abstract

A case of salmonella infrarenal aortic aneurysm that ruptured and was treated with staged operative procedures and a highly effective antibiotic is reported and analyzed. An emergency situation with a ruptured abdominal aortic aneurysm required prompt surgical intervention with an aortobifemoral graft insertion. In the immediate postoperative period it was realized that a prosthetic graft was placed in the bed of a mycotic aneurysm. The patient had significant arteriosclerotic occlusive disease limiting the distal anastomotic site to the common femorals. Interoperatively the superficial femorals were noted to be occluded chronically. Consequently, revascularization via an extra- anatomical bypass after aortobifemoral graft removal was more complex. This was managed in a staged delayed fashion, while suppressing the infecting organism with Cefotaxime. The details of this complex situation are described within.
