Since 1971, percutaneous transluminal angioplasty of peripheral arteries has been performed in 225 patients. There was an overall patency rate of 70-80% after 2 years. Our technique was then adapted and modified to perform coronary dilatation. This was performed successfully in 8 dogs in which selective coronary artery stenosis war induced by silk ligature and secondary inflammatory changes. The technique was then applied to the coronary lesions in postmortal humans and tested in the operating room during A-C bypass to evaluate vessel patency, peripheral debris etc.
自1971年以来，已对225例患者进行了外周动脉经皮腔内血管成形术。两年后的总体通畅率为70 - 80%。随后我们对技术进行了调整和改进以用于冠状动脉扩张。在8只通过丝线结扎诱导选择性冠状动脉狭窄并继发炎症改变的犬身上成功进行了该操作。然后将该技术应用于死后人体的冠状动脉病变，并在冠状动脉搭桥手术期间在手术室进行测试，以评估血管通畅情况、外周碎屑等。
