Two hundred and forty percutaneous transluminal coronary angioplasty procedures were performed in three centres over a two year period. Acute occlusion of the vessel undergoing angioplasty was seen on 20 (8%) occasions. The cause of occlusion was determined angiographically and in some cases confirmed at the time of emergency open heart surgery. The mechanism of coronary occlusion was arterial dissection in six cases, persisting coronary arterial spasm in seven, and coronary thrombosis in four. In three patients the mechanism could not be determined. Immediate reintroduction of a balloon dilatation catheter was attempted in 10 patients and resulted in restoration of adequate coronary flow in six. The remaining 14 patients underwent open heart surgery as an emergency procedure.
在两年时间里，三个中心共进行了240例经皮腔内冠状动脉成形术。血管成形术中血管急性闭塞的情况出现了20次（8%）。通过血管造影确定了闭塞原因，部分病例在急诊心脏直视手术时得到证实。冠状动脉闭塞的机制为动脉夹层6例、持续性冠状动脉痉挛7例、冠状动脉血栓形成4例。3例患者的机制无法确定。10例患者尝试立即重新插入球囊扩张导管，其中6例恢复了足够的冠状动脉血流。其余14例患者作为急诊手术接受了心脏直视手术。
