Mediastinitis caused by methicillin-resistant Staphylococcus aureus（MRSA）is a severe complication after coronary artery bypass grafting（CABG). Vacuum-Assisted Closure（VAC）therapy is a technical innovation in wound care. The advantage of VAC is the application of negative pressure to sternal wounds. A 73-year-old man was admitted to our hospital because of operation for triple vessel disease including left main coronary artery lesion. Off-pump CABG was performed using the bilateral internal thoracic arteries and right gastroepiploic artery. The postoperative course was uneventful. However, purulent discharge from a median sternostomy wound appeared on the 11th postoperative day. MRSA was identified by the culture of the wound exudate. On operation, the necrotic tissue was removed, and continuous irrigation and drainage were performed. Conventional technique was not effective. VAC therapy was applied on the 35th postoperative day. During VAC therapy, the wound became smaller and granulation tissue proliferated. VAC therapy was discontinued on the 208th postoperative day. Finally, the wound was naturally closed. He was discharged in good condition on the 213th postoperative day. VAC therapy was an effective treatment for MRSA mediastinitis after cardiac surgery.
