To evaluate the efficacy of percutaneous transluminal angioplasty as a possible alternative to repeated open heart surgery for symptomatic aortocoronary saphenous vein graft stenoses, the procedure was initiated at Shadyside Hospital in January 1978. Percutaneous transluminal angioplasty has been used in nine aortocoronary graft stenoses and 11 native coronary artery stenoses. Of the nine grafts, eight (88 percent) were successfully dilated, including three that had been totally closed as visualized by angiography. Of the 11 coronary dilations, only four (36 percent) resulted in improved flow. The more favorable results experienced with the graft dilations was thought to be due to the nature of the occlusive processes affecting these grafts. The fibrous intimal proliferative disease that is found in most grafts is easily compressible, while the nature of the disease in the coronary arteries is not so readily predictable. Better instrumentation and careful evaluation before and after angioplasty will improve the results and extend the indications for coronary artery and saphenous vein graft transluminal angioplasty.
为评估经皮腔内血管成形术作为症状性主动脉冠状动脉大隐静脉移植血管狭窄反复进行心脏直视手术的一种可能替代方法的疗效，1978年1月在沙迪赛德医院开展了该手术。经皮腔内血管成形术已用于9例主动脉冠状动脉移植血管狭窄和11例自身冠状动脉狭窄。在9例移植血管中，8例（88%）成功扩张，其中3例经血管造影显示已完全闭塞。在11例冠状动脉扩张中，只有4例（36%）血流得到改善。移植血管扩张取得更理想结果被认为是由于影响这些移植血管的闭塞过程的性质所致。大多数移植血管中发现的纤维内膜增生性疾病易于被压缩，而冠状动脉疾病的性质则不那么容易预测。更好的器械以及血管成形术前后的仔细评估将改善结果并扩大冠状动脉和大隐静脉移植血管腔内血管成形术的适应证。
