升主动脉—冠状动脉旁路术是70年代心血管外科一项突出成就,但对手术疗效则一直持有不同看法。随着手术数字大量增加,争论也更趋激烈。有的作者提出:冠状动脉旁路术本身就是一种姑息性手术,它不能制止病变的发展,反而加重或加速闭塞性疾病的进展,它不能予防心肌梗塞,在术中还可能产生新的心肌梗塞等。特别因冠脉旁路术是针对冠状动脉不同的解剖病变和临床表现,有多种移植方法,并常需移植多根血管桥。条件不尽相同,结果自然迥异,所以对手术疗效评价,必须做具体分析。近10余年来内外科治疗冠心病都取得显著的进展,但内科疗法目前尚无法取代 Ascending aorta - coronary artery bypass surgery is a prominent achievement in cardiovascular surgery in the 70s, but the surgical efficacy has always held a different view. As the number of surgeries has increased substantially, the debate has intensified. Some authors suggest that coronary artery bypass surgery itself is a palliative surgery, it can not stop the development of the disease, but aggravate or accelerate the progress of occlusive disease, it can not be against myocardial infarction, intraoperative may also produce new myocardium Infarction and so on. In particular, due to coronary artery bypass grafting different anatomical lesions and clinical manifestations of the coronary artery, there are a variety of transplantation methods, and often need to transplant multiple vascular bridge. Different conditions, the results are naturally different, so the evaluation of the efficacy of surgery, we must do a specific analysis. In the past 10 years, surgical treatment of coronary heart disease have made significant progress, but medical therapy is currently unable to replace
