title: [Off-pump coronary artery bypass grafting: comparison between standard CABG and off-pump CABG].
abstract: We have performed 321 cases of coronary artery bypass grafting (CABG), between October 15 1995 and November 20 2000. We have evaluated the operative results of 142 cases (44.2%) of conventional CABG and 179 cases (55.8%) of off-pump CABG performed during this period. The average numbers of bypassed grafts was 3.53 for conventional CABG, and 1.62 for off-pump CABG. The total number of 369 grafts were anastomosed to 501 coronary arteries for conventional CABG, and 283 grafts were anastomosed to 290 coronary arteries for off-pump CABG.
  
  
  RESULTS
  Although two saphenous veins were occluded, the early postoperative patency rate was 100% for conventional CABG using RITA, LITA, GEA and RA. Three site of stenosis in 18 LITAs and 2 in 16 RITAs were recognized in off-pump CABG without the use of stabilizers. One site of stenosis in 130 LITAs and 3 string signs in 44 GEA were recognized in off-pump CABG with the use of stabilizers. Postoperative angiography in 52 off-pump CABG cases at one year later showed no new lesion.
  
  
  CONCLUSIONS
  The use of stabilizers and LIMA suture enables adaptation of the MIDCAB procedure to a wider range of coronary artery bypass procedures, and a higher graft patency can be expected.
