A deep sternal wound infection (DSWI) can become a severe complication after cardiac surgery, with in-hospital mortality rates reaching up to 35%. Staphylococci, particularly methicillin resistant Staphylococcus aureus (MRSA), play important roles in its etiology.
This case report presents a patient who underwent coronary artery bypass surgery, and suffered postoperatively from a DSWI caused by MRSA. The pathogen was susceptible to vancomycin and rifampicin in vitro; however, this therapy was clinically ineffective. Both clinical improvement and MRSA eradication were achieved after surgical debridement of the wound and the intravenous administration of dalbavancin.
We decided to administer dalbavancin because of its convenient pharmacological profile. The patient’s tolerance of the antimicrobial was good, the biochemical markers of inflammation returned to the normal ranges, and the microbiological results one week after the dalbavancin administration were negative. A good clinical outcome was achieved with both the surgery and antimicrobial administration. In this case, dalbavancin was more effective in the treatment of the sternal and surrounding tissue infections caused by MRSA, when compared to vancomycin.
