A Case of Mycotic Deep Femoral Artery Aneurysm due to Helicobacter cinaedi Bacteremia

Abstract

A 60-year-old woman with end-stage renal disease on hemodialysis, peripheral artery disease, chronic rheumatoid arthritis, and multi-drug resistant tuberculosis had complained of fever, left inguinal swelling, and pain. The level of CRP was 17.5 mg/dl and computed tomography displayed a left deep femoral artery pseudoaneurysm. We performed an emergency resection of the aneurysm and debridement. On day 5, Helicobacter cinaedi (H. cinaedi) was detected by blood culture. Imipenem-cilastatin was administered for 10 days and the antibiotic was switched to sulbactam-ampicillin for 1 month. There has been no recurrence for a period of 4 months. H. cinaedi could be a source of mycotic aneurysm in immunocompromised patients.
