[Methicillin-resistant Staphylococcus aureus (MRSA) mediastinitis after cardiovascular operations].

We described three cases of poststernotomy mediastinitis caused by MRSA. The first case 74-year-old woman who had undergone emergent CABG was treated by continuous closed irrigation and consecutive omental transfer. She was suffered from multiple organ failure and died. The other two cases 50-year-old woman and 66-year-old man after double valves replacement and total aortic arch replacement were managed successfully with simultaneous combination of surgical debridement and placement of omental flap. It was seemed that early aggressive surgical procedures before deterioration of general conditions associated with improvement of mortality. Additionally, it was considered that to avoid residual dead space in presternum as well as in mediastinum was essential to decrease the morbidity and hospital stay, especially in case of MRSA infection.
