The results of 126 consecutive balloon dilatations of coronary arteries, carried out in 110 patients between 1980 and the end of 1983, are reported. The follow-up periods ranged from one to 47 months. The primary success rate was 74%, and the long-term success rate was 65%. In successful cases, the diameter of stenosis was changed, on average, from an initial 88% to 33%. Acute occlusion of the vessel occurred on 13 occasions (10%). Of these, myocardial infarction occurred in eight (6%), and emergency bypass grafts were performed in nine (7%). One of these 13 patients died (case fatality rate, 0.8%). Occlusion of the dilated vessels did not occur after the patients were discharged from hospital. However, stenosis recurred in 20 of 80 patients with successfully dilated arteries (25%). Dilatation was repeated in 16 of these, and stenosis had not recurred at the three-months' follow-up. There has been a marked improvement in the success rate of this procedure over the years. It is concluded that balloon dilatation is an effective and safe alternative to bypass graft surgery in selected patients with coronary artery disease.
本文报告了1980年至1983年底期间对110例患者进行的126次冠状动脉球囊扩张术的结果。随访时间为1至47个月。初次成功率为74%，长期成功率为65%。成功病例中，狭窄直径平均从最初的88%降至33%。血管急性闭塞发生13次（10%）。其中，8例（6%）发生心肌梗死，9例（7%）进行了急诊搭桥手术。这13例患者中有1例死亡（病死率0.8%）。患者出院后未发生扩张血管闭塞。然而，80例成功扩张动脉的患者中有20例（25%）出现狭窄复发。其中16例再次进行了扩张，在三个月随访时狭窄未复发。多年来该手术的成功率有了显著提高。结论是，对于选定的冠心病患者，球囊扩张术是一种有效且安全的替代搭桥手术的方法。
