A Case of Infected Abdominal Aortic Aneurysm Caused by Citrobacter

Abstract

A 73-year-old man underwent emergency surgery under a diagnosis of impending rupture of infected abdominal aortic aneurysm. The infected aneurysm and surrounding tissues were resected en bloc and replaced with a rifampicin-soaked bifurcated dacron graft. The prosthesis and anastomoses were covered with the harvested omental flap. Citrobacter freundii was identified in a blood culture and on the aneurysmal wall. The postoperative course was uneventful without any infectious complications, and he was discharged 25 days after surgery.
