Objective To evaluate the clinical outcomes of off pump coronary artery bypass grafting (OPCAB).Methods OPCAB were performed via sternotomy,using stabilizer,deep pericardial retraction sutures,shunt and blower.Results Left mammary arteries were used for all patients,average graft number was 2.6 (from 1～4), average operating time was 161 minutes,intraoperative blood loss was 320?ml.One patient switched to conventional coronary artery bypass grafting.Postoperative average drainage in 24 hours was 380?ml,and average blood transfusion was 320 ml.Four patients were extubated in operating room.Average mechanical ventilation time was 4.2 hours,average ICU stay was 12.6 hours and average hospital stay was 12.5 days.One patient died from severe pulmonary infection in 2 weeks postoperatively.The hospital mortality was 3.3%.Angina disappeared in all patients in a 1 to 7 month period of follow up.Conclusions OPCAB is a minimally invasive,safe,effective and economical technique,and can be used for single and multiple vessel disease as well as high risk factor patients.This technique was recommended to widely use for coronary artery bypass grafting. |
