Off-pump coronary artery bypass grafting for severe coronary atherosclerotic heart disease / 中国微创外科杂志

ABSTRACT

Objective To explore the feasibility of off-pump coronary artery bypass grafting (OPCAB) in the treatment of severe coronary atherosclerotic heart disease. Methods Clinical data of 37 cases of severe coronary heart disease from January to December, 2002, were retrospectively reviewed. All operations were conducted under general anesthesia by midline sternotomy. The left internal mammary artery (LIMA) and the great saphenous vein (SV) were divided for grafting. Then we stabilified the local myocardium and exposed the diseased coronary arteries. Following the insertion of an intracoronary shunt, the LIMA was anastomosed to the left anterior descending artery (LAD). Afterwards, the SV was proximally anastomosed to the aorta, and then, to the coronary artery. Results All the operations were completed by beating heart revascularization. The number of bypass grafting was 3 2?0 5 (range, 1～6). Except 1 patient died on the 10th postoperative day, no severe complications, such as peri-operative myocardial infarction, respiratory failure, renal insufficiency or cerebrovascular accident, took place in the remaining 36 patients. Conclusions In the context of skillful procedure techniques and strict peri-operative management, OPCAB in the treatment of severe coronary atherosclerotic heart disease is feasible.
