[Procedure and problem for short-term outcomes on off-pump coronary artery bypass grafting]

We performed off-pump coronary artery bypass grafting (CABG) in all cases without reoperation case from July, 2002. Advantage of off-pump CABG versus on-pump CABG which is reduced a number of perioperative complication and early patients recovery was previously demonstrated. In our institute, the mean number of grafts per patients was 4.7 +/- 1.3, and the rate of using arterial grafts was 99.5% in all cases without minimally invasive direct coronary artery bypass (MIDCAB). The mean hospital stay after operation was 10.8 +/- 2.8. It was shorted remarkably in comparison with on-pump CABG; 19.4 +/- 6. Furthermore, sever complication was not occurred in any cases after operation though high risk cases were increased. In the early cases, atrial fibrillation complicated frequently (32%), but using after magnesium sulfate it was remarkably decreased (8.4%). On the other-hand, attention is necessary for the infection caused by the increase of high risk patients. Therefore, we used vancomycin (VCM) at these cases from the viewpoint of prevention. Recently, we performed remnant omental transfer for the sever diabetes mellitus case which was used bilateral internal thoracic artery on CABG. It learned to get the early recovery which was necessary for the off-pump CABG by the above additional treatment.
