[Vacuum assisted closure for postoperative mediastinitis using a portable aspirator].

We report a case of successful treatment of a methicillin resistant Staphylococcus aureus (MRSA) mediastinitis by vacuum assisted closure (VAC) using SB VAC system as a portable aspirator. A 67-year-old male with intellectual disability and diabetes mellitus suffered from angina pectoris and underwent on-pump coronary artery bypass grafting. He had a MRSA mediastinitis following the surgery. We started vancomycin administration and VAC. It was expected that using wall suction for VAC would be difficult because of his intellectual disability. So we performed VAC using SB VAC system as a portable aspirator. VAC therapy for mediastinitis after cardiac surgery is effective and SB VAC system can be used as a portable aspirator.
