Abstract:
Objective To analyze the feasibility and superiority of off-pump coronary artery bypass grafting(OPCAB) in patients with left main coronary lesions.Methods A retrospective study was carried out to review our experience on 392 cases with left main coronary lesions,who underwent CABG in our hospital.Among the cases,279 patients(71.2%) underwent OPCAB and 113 cases received CCABG.The early postoperative mortality and complications of the two groups were compared.Results The number of bypass grafts was(4.17?0.86) in Group OPCAB and(4.24?0.94) in Group CCABG,showing no significant difference between them(t=-0.710,P=0.478).No significant difference was detected in peri-and post-operative morbidity between the two groups [atrial fibrillation: 31(11.1%) vs 8(7.1%),?2=1.459,P=0.227;perioperative myocardial infarction: 7(2.5%) vs 3(2.7%),?2=0.000,P=1.000;renal inefficiency: 9(3.2%) vs 4(3.5%),?2=0.000,P=1.000;pulmonary complications: 15(5.4%) vs 6(5.3%),?2=0.000,P=1.000].The early postoperative mortality of Group OPCAB was significantly lower than that in Group CCABG[2(0.7%) vs 5(4.4%),?2=4.368,P=0.037].The time of intubation[20(8-48) h vs 51(14-130) h,Z=-2.823,P= 0.005],ICU-stay [51(38-141) h vs 92(42-352) h,Z=-2.618,P=0.009],volume of transfusion [500(200-1200) ml vs 800(400-2100) ml,Z=-2.411,P= 0.016],re-open [5(1.8%) vs 10(8.8%),?2=9.052,P=0.003] and complication of CNS [3(1.1%) vs 9(8.0%),?2=10.647,P=0.001] of Group OPCAB were significantly less than that of Group CCABG.Conclusions It is feasible,safe and effective to perform OPCAB in patients with left main coronary lesions.
