On-pump coronary artery bypass grafting:a report of 350 cases / 局解手术学杂志

ABSTRACT

Objective To summarize the clinical experiences of coronary artery bypass grafting ( CABG) in the treatment of coronary artery disease. Methods CABG were performed on 395 consecutive cases from January 2002 to December 2012,including 299 male and 96 female with a mean age of 62. 3 years old. All the operation were performed under cardiopulmonary bypass (CPB ) with moderate hypothermi-a. Left ventricular aneurysm plasty operation were performed in 18 patients. Results The mean number of grafts was 3. 2,the mean CPB time was 88 min( 62~170 min) ,aortic cross-clamping time was 68 min( 25~102 min) ,mean ventilation time was 18 h( 12~72 h) . There were 8 deaths with a mortality of 2. 0%. Six patients died of multiple organ failure,1 patients died of ventricular fibrillation after operation,1 patients died of acute myocardial infarction. Postoperative follow up was carried out on 280 cases,follow-up time was from 8 months to 11 years. Five of them died of unknow causes. The heart function of the rest was significantly improved. 195 patients were free of angina. 85 pa-tients’ s symptom got better. Conclusion CABG performed under cardiopulmonary bypass ( CPB ) with moderate hypothermia is safe and effective for the treatment of coronary artery disease.
