Here we describe a case involving an elderly man with Citrobacter
freundii-associated infectious rupture of a dissecting thoracoabdominal
aortic aneurysm. We performed emergency thoracoabdominal aortic
replacement using a rifampicin-soaked prosthetic graft and omental flap
wrapping. The patient was discharged on postoperative day 255, although
he experienced pseudomembranous enteritis and paraplegia.
