Coronary occlusion is the most serious complication of percutaneous transluminal angioplasty. In 440 cases coronary occlusion occurred in 22 patients (5%). Treatment was coronary bypass in 12 cases mechanical recanalization in 7 cases and coronary bypass after unsuccessful mechanical recanalization in 3 cases. One patient died after mechanical recanalization and 9 (41%) had myocardial infarction confirmed by electrocardiography and angiography. The number of coronary occlusions increased initially but decreased with improvements in materials and techniques. It is concluded that coronary occlusion is a severe but rare complication of percutaneous angioplasty. Mechanical recanalization should be attempted, and in case of failure the patient should be referred for surgery. In the large majority of cases the outcome is benign.
冠状动脉闭塞是经皮腔内血管成形术最严重的并发症。在440例患者中，有22例（5%）发生了冠状动脉闭塞。治疗方法为12例行冠状动脉搭桥术，7例行机械再通术，3例在机械再通术失败后行冠状动脉搭桥术。1例患者在机械再通术后死亡，9例（41%）经心电图和血管造影证实发生心肌梗死。冠状动脉闭塞的例数最初有所增加，但随着材料和技术的改进而减少。结论是冠状动脉闭塞是经皮血管成形术的一种严重但罕见的并发症。应尝试进行机械再通，若失败则应将患者转诊进行手术。在大多数情况下，预后良好。
