Two Cases of Mycobacterium fortuitum Infection after Open-Heart Surgery / 日本心臓血管外科学会雑誌

ABSTRACT

Mycobacterial infection after open-heart surgery is a rare complication. We report 2 cases of cutaneous infection caused by <i>Mycobacterium fortuitum</i> (<i>M. fortuitum</i>). Case 1 A 56-year-old man had wound infection from the 10th postoperative day (POD). The growth of <i>M. fortuitum</i> was detected on the 38th POD. Combination of multiple antibiotic therapy was performed. He was cured after several recurrences of cutaneous ulcer and abscess following 15 months. Case 2 A 26-year-old man had wound infection from the 28th POD. Deep sternal infection with mediastinitis developed. Bacteriological examination revealed the growth of <i>M. fortuitum</i> on the 61st POD. Omentopexy was performed on the 67th POD. Wound infection completely healed, and the patient was discharged from our hospital on the 137th POD. Mycobacterial infection should be considered when the wound infection is resistant to ordina antibiotics.
