经皮冠状动脉成形术的临床研究

Clinical study of percutaneous transluminal coronary angioplasty

目的探讨应用经皮冠状动脉成形术（ＰＴＣＡ）治疗冠心病的临床效果。方法４２例冠心病患者经选择性冠状动脉造影术证实２７例为单支病变，１３例为双支病变，２例为三支病变；５９支病变血管中左前降支（ＬＡＤ）３５支，左回旋支（ＬＣＸ）７支，右冠状动脉（ＲＣＡ）１７支；狭窄程度为７５～１００％。采用Ｇｒｕｅｎｔｚｉｇ等建立的方法进行ＰＴＣＡ。结果４２例患者扩张成功４０例，成功率为９５．２％；５９支病变血管扩张成功５３支，成功率为８９．８％；７５处狭窄扩张成功６６处，成功率为８８％。术后４０例扩张成功患者的症状均得以缓解或消失。结论ＰＴＣＡ对冠心病有显著的治疗效果，但应注意术中的一些问题并防止并发症的发生。

Objective To research clinical effect of treating coronary heart disease with percutaneous transluminal coronary angioplasty(PTCA). Methods In 42 patients with coronary heart disease, 27cases of the single branch lesions ,13 cases of the double branch lesions and 2 cases of the three branch lesions were confirmed by selective coronary angiography; In 59 branches with lesion vessels, there were 35 branches of the left anterior descending coronary arteries (LAD), 7 branches of the left circumflex coronary arteries (LCX) and 17 branches of the right coronary arteries(RCA). The narrow degrees varied from 75% to 100%. PTCA was performed with Gruentzig's method.Results 40 of 42 patients, 53 of 59 branches with lesion vessels and 66 of 75 narrow parts were dilated successfully. The successful rates were 95.2%, 89.8%, 88%, respectively. Symptoms of the successful 40 patients were improved obviously or disappeared after PTCA. Conclusion PTCA has a better therapeutic effect for coronary heart disease, but we ought to pay attention to some problems in PTCA and prevent complications.
