In recent years, percutaneous transluminal coronary angioplasty (PTCA) has been actively carried out as a therapeutic method of the ischemic cardiopathies, and Stent therapy has been clinically applied as settlement method of problematical points of the acute occlusion and dissection of the coronary artery by PTCA. We experienced 6 cases necessitated coronary artery bypass graft (CABG) after insertion of Palmaz-Schatz Stent until March 1992. The emergent bypass was carried out in 3 of 6 cases because thrombotic occlusion developed although Stent was inserted in thrombotic occlusion after PTCA, while 2 cases were not life-saved because of the cardiac function was worsened before operation. Other 3 cases were life-saved by expectant treatment even though stenosis developed again after Stent therapy. Stent therapy is a useful method, while severity in cases using CABG and operative complexity are expected by development of new problematical point in the future.
近年来，经皮腔内冠状动脉成形术（PTCA）作为缺血性心脏病的一种治疗方法已得到积极开展，支架治疗已在临床上作为解决PTCA导致的冠状动脉急性闭塞和夹层等问题的方法应用。截至1992年3月，我们共经历了6例在植入Palmaz-Schatz支架后需要进行冠状动脉旁路移植术（CABG）的病例。6例中有3例进行了急诊旁路手术，因为尽管在PTCA后发生血栓形成闭塞时已植入支架，但仍出现了血栓性闭塞，而另外2例因术前心功能恶化未能挽救生命。另外3例尽管在支架治疗后再次出现狭窄，但通过保守治疗得以挽救生命。支架治疗是一种有用的方法，然而未来新问题的出现可能会增加使用CABG病例的严重性和手术复杂性。
