Percutaneous transluminal coronary angioplasty was performed in a 56 year old man with postinfarction angina. During an otherwise uncomplicated dilatation of a left anterior descending artery with a 70% stenosis two diagonal branches, each measuring 1.5 mm in diameter, were occluded. The occlusions were not associated with any adverse clinical effects, though there was a small rise in plasma creatine kinase concentration. The patient became free of angina two weeks after angioplasty, and follow up angiography showed spontaneous reappearance of the occluded side branches. Redistribution of atheromatous material and its later reabsorption may have been the mechanism for the initial occlusion and later reappearance of the vessels.
对一名患有心肌梗死后心绞痛的56岁男性进行了经皮腔内冠状动脉成形术。在对一支狭窄70%的左前降支进行的无并发症扩张过程中，两条直径均为1.5毫米的对角支被闭塞。尽管血浆肌酸激酶浓度略有升高，但这些闭塞并未产生任何不良临床影响。该患者在血管成形术后两周心绞痛消失，随访血管造影显示闭塞的侧支自发重新出现。动脉粥样硬化物质的重新分布及其随后的再吸收可能是血管最初闭塞及随后重新出现的机制。
