Listeria monocytogenes infection of a prosthetic vascular graft.

A 75-year-old man was admitted for acute ischaemia of his right leg for which he had undergone vascular prosthetic surgery at another hospital, ten and three years before. Cultures of the thrombosed graft and the clots removed on re-operation were positive for Listeria monocytogenes. After parenteral treatment with amoxicillin-clavulanic acid and gentamicin, the patient died from cardiorespiratory failure.
