Listeria monocytogenes as a rare cause of mycotic aortic aneurysm.

Abstract

Mycotic aneurysms represent a diagnostic and therapeutic challenge still lacking general recommendations for optimal therapy. So far, Listeria monocytogenes (L. monocytogenes) is very rarely reported to be the causative organism of mycotic aortic aneurysms. We report 2 cases of mycotic abdominal aortic aneurysms due to L. monocytogenes infection being treated by radical debridement, open in situ reconstruction with aorto-bi-iliac Dacron grafts, and long-term antibiotic therapy. Both patients recovered well from surgery. Interestingly, the long-time follow-up for the first patient 9 years after surgery was entirely uneventful. Open debridement in an in situ reconstruction with Dacron grafts followed by antibiotic therapy seems to be a suitable therapeutic regime for mycotic aneurysms due to L. monocytogenes.
