Introduction
The omentum is an effective and potent tissue that can treat deep sternal wound infections because of its immunological properties1. Many studies reported the utility of an omental flap for severe mediastinitis after cardiac surgery2-4. Few reports described re-sternotomy after an omental flap procedure5, although there have been some similar reports6, 7. Thick adhesions may be present after surgical treatment for mediastinitis8, and detection of the targeted coronary arteries may be extremely difficult after surgical treatment for mediastinitis because of severe adhesion9, 10. We report a 78-year-old-man who underwent re-sternotomy using CABG after omental flap for mediastinitis that was safely and successfully performed with a circular electric sternum saw.
