Clostridium septicum aortitis causing aortic dissection in a 22-year-old man

Tex Heart Inst J. 2009;36(4):334-6.


Clostridium septicum infection is a rare cause of aortic dissection, and the mortality rate for the condition is high. Only 26 cases of C. septicum aortitis have been reported; all of those patients were elderly, and 20 of them had an associated colonic neoplasm. Herein, we present the case of a 22-year-old man whose C. septicum aortitis resulted in aortic dissection that involved the entire length of the aorta. Upon autopsy, no neoplasm or other predisposing condition was identified in this patient. To the best of our knowledge, this is the 1st report of C. septicum aortitis, fatal or otherwise, in a young individual.
