[A new case of arterial Listeria infection]

Listeria monocytogenes arterial infections are uncommon and usually occur on aneurysms of previously operated arteries, classically in very young and very old or immunodepressed subjects. Peroperative samples for bacteriology should always be taken as antibiotics generally used in vascular surgery are ineffective against listeria. We report a case of a patient who underwent emergency surgery. Bacteriologic analysis of the thrombus revealed listeria inoculation which was eradicated by adapted antibiotic treatment.
