Objective To compare the clinical early results of on-pump and off-pump coronary artery bypass grafting re-operations (re-CABG)and introduce our experience. Methods From April 2000 to June 2006, 21 cases with coronary artery diease of re-CABG were performed in this hospital. 10 patients received off-pump CABG (off-pump group), and 11 underwent CABG re-operations with cardiopulmonary bypass CABG(on-pump group). There were no significant difference regarding gender, age, weight, diabetes, hypertension, left ventricular end-diastolic dimension (LVEDD) and left ventricular ejection fraction (LVEF) between two groups before operation. On-pump CABG procedures were performed on hypothermia cardiopulmonary bypass. Standard methods were used to finish off-pump CABG. Flow meters were utilized to measure the flow of grafts in both groups. Results No one in off-pump group needed to conver to on-pump CABG. There was no operative or late mortality. The operation time, respiratory support time, the volume of chest tube drainage, blood transfusion and postoperative hospital stay were less in off-pump group than those in on-pump group after operation. Early death occurred in 1 patient in on-pump group. The number of distal anastomosis were more in on-pump group than that in off-pump group. Conclusions Both off-pump CABG and on-pump CABG can be applied to CABG re-operations and achieved similar completeness of revascularization, similar early surgical results.
