摘要(Abstract)：

目的本研究旨在评估原位冠状动脉在冠状动脉旁路移植术(CABG)后的通畅率以及分析其进展为慢性完全闭塞(CTO)病变的危险因素。方法回顾性分析南京医科大学第一附属医院CABG术后因再发心绞痛复查冠状动脉造影患者44例,对其原位冠状动脉通畅率、病变进展程度以及其影响因素进行分析,并评估针对原位冠状动脉行经皮冠状动脉介入治疗(PCI)的效果。结果 44例患者CABG术前冠状动脉造影有21例(47.7%)至少存在1支原位冠状动脉CTO病变,CTO病变血管总数为26支(59.1%);CABG术后复查造影,10例(22.7%)原位冠状动脉进展为CTO病变;CABG术前狭窄>90%的原位冠状动脉进展为CTO的概率是狭窄<90%血管的3.9倍(70.0%比17.9%,P=0.005)。logistic多因素回归分析,术前左前降支(LAD)狭窄>90%是原位冠状动脉LAD新发CTO的独立危险因素(OR 27.217,95%CI 1.801～411.268,P=0.017)。44例患者中有22例患者共30处原位冠状动脉病变具有PCI适应证,除1处因血管迂曲钙化,导丝不能通过而失败外,余29处(96.7%)均成功置入了药物洗脱支架(共63枚)。结论 CABG术后原位冠状动脉进展为CTO病变并不少见。CABG术前原位冠状动脉狭窄> 90%可能是其重要的预测因素之一。针对CABG术后的原位冠状动脉行PCI是可行的。
