Introduction
Infectious aortic aneurysms are relatively rare and account for 0.7%–3.0% of all aortic aneurysms.1 However, surgical management protocols for such cases are not well defined, and postoperative infection control remains a concern.
Infectious aneurysms caused by Citrobacter freundii 2 are rare. Herein, we report a case of infectious rupture of a dissecting thoracoabdominal aortic aneurysm (TAAA) caused by C. freundii , which was successfully treated with anatomical revascularization using a rifampicin-soaked prosthetic aortic graft and omental flap wrapping.
