Conclusion
We encountered a rare case of infectious TAAA due to C. freundiiinvasion of a preexisting dissecting aortic lesion, which led to aortic
rupture within a week. AmpC production by the organism required
administration of carbapenem antibiotics that resulted in
pseudomembranous enteritis. The findings suggest that C.
freundii , an opportunistic bacterium, can infect residual dissections
in the descending aorta, and the resulting infectious aortic aneurysm
could rupture in a week. A rifampicin-soaked prosthesis and omental flap
wrapping may be effective methods to prevent vascular prosthesis
infection.
