经皮冠状动脉腔内成形术(PTCA)治疗冠状动脉疾患,尤其是治疗单支或双支血管病变已被广泛地应用于临床。在美国.仅1986年就施行了133,000例此种手术。另一方面,冠状动脉旁路血管移植术(搭桥术,A-C bypass)亦早已成功地治疗单支或双支冠状动脉疾患。近年来,在很多医疗中心风靡一时地作了大量PTCA手术,这是因为①PTCA与A-C bypass具有相似的成功率②对病人较为安全,③住院期短,④费用低.但是这两种手术的远期疗效如何?本文着重研究和比较了这两种手术后三年的效果。
Percutaneous transluminal coronary angioplasty (PTCA) in the treatment of coronary artery disease, especially for the treatment of single or double vessel disease has been widely used in clinical. In the United States alone, 133,000 such procedures were performed in 1986. On the other hand, coronary artery bypass grafting (A-C bypass) has long been successful in treating single or double coronary artery disease. In recent years, a large number of PTCA operations have been performed in many medical centers because of the similar success rate of PTCA and AC bypass, which is safer for patients, shorter hospital stay and lower costs, but the two operations are far How effective is this period? This article focuses on the study and comparison of the effects of these three post-surgery three years.
