  • Offpump and Onpump Coronary Artery Bypass Grafting: A Report of 698 Cases

    Objective To summarize the experiences of off-pump coronary artery bypass grafting (off-pump CABG) and on-pump coronary artery bypass grafting (onpump CABG) for patients with coronary artery diseases and to improve the surgical techniques and clinical results. Methods Coronary artery bypass grafting(CABG) were performed from January 2000 to March 2009 on 698 consecutive cases, including 551 male and 147 female with a mean age of 67.2 years(range, 28.0-79.0). There were 552 cases with angina pectoris and 131 with old myocardial infarction. Preoperative cardiac function showed 301 cases in New York Heart Association classⅡ, 339 in class Ⅲ,and 58 in class Ⅳ. Coronary angiography revealed single vessel disease in 21 cases, 2vessel disease in 87, 3vessel disease in 590, and 201 cases had concomitant left main lesions.There were 687 elective CABG and 11 emergency / urgent ones. Offpump CABG were performed on 346 cases and the others received onpump CABG . Results A total number of 2 025 grafts ( range,1-6 grafts, mean, 2.9 grafts /case ) were constructed with 693 left internal mammary arteries,115 free right mammary arteries,229 left radial arteries, and 81 right radial arteries. Total arterial bypass grafting was feasible on 126 cases. Postoperative ventilation duration varied from 0-127 hours (mean, 11.5 hours). Fasttrack procedure was offered to 38 cases with good results.Introaortic balloon pump support were provided to 1 patient preoperatively and 27 postoperatively. There were 25 deaths with a mortality of 3.64% for the elective cases with the cause of acute myocardial infarction ( 5 cases ), low cardiac output syndrome (3 cases),protamine reaction (2 cases),respiratory failure (3 cases), renal failure (2 cases),and multiorgan failure (10 cases).Four deaths occurred to urgent cases with a mortality of 36.36% from low cardiac output syndrome ( 3 cases) and acute myocardial infarction (1 case). One hundred and fiftyone cases(21.63%)developed atrial fibrilation among which 147(97.35%)returned to sinus rhythem with administration of electrolytes and Amiodarone. Resternotomy were performed for bleeding in 12 cases. Upon discharge from the hospital, 511 patients were free from angina while 20 other patients still had coexisting relieved angina. Postoperative followup was carried out on 415 cases(62.03%)for a period of 1month to 8.2 years with 3 deaths for lung cancer (1 case), car accident(1case), and unknown reasons (1 case). Number of patients who were free from angina was 317 and 21 for those who had recurrent angina. The cardiac function improved with 269 cases(65.29%)in New York Heart Association class Ⅱ, 142(34.46%)class Ⅲ, and 1(0.24%) class Ⅳ. Conclusion Good surgical results could be achieved with careful analysis of native Chinese patients’ coronary vessels, individualized operative plan, control of operative risk factors, and proper selection of bypass conduits. Aggressive use of IABP can provide essential support for patients with poor left ventricular function and other high risk factors.
