AbstractAortic stent-graft infection after endovascular abdominal aortic aneurysm (AAA) repair is an uncommon, but very serious complication with potentially devastating consequences.(1) Traditional open techniques of repair of AAA demonstrate an infection rate of 0.5-3%. The exact rate of infection with endovascular repair is unknown, but literature review demonstrates an overall incidence of 0.43-1.17% retrospectively.(2,3) Etiology of endovascular graft infections typically results from flora derived from the skin or gastrointestinal tract.(4)Clostridium septicum is a naturally occurring anaerobic bacterium native to the gastrointestinal tract. It is typically associated with spontaneous nontraumatic gas gangrene owing to bacteremia from the gastrointestinal tract with an incidence rate of 0.07%.(5) To our knowledge, this is the first reported case of endovascular AAA graft infection owing to Clostridium septicum species.Copyright © 2011 Annals of Vascular Surgery Inc.
