摘要(Abstract)：

<正>冠状动脉分叉病变15%～20%的患者行经皮冠状动脉介入治疗(percutaneous coronary intervention,PCI),然而其治疗效果仍然堪忧[1]。冠状动脉造影(coronary angiography,CAG)能提供关于分叉病变处解剖变化、斑块位置和支架位置等信息,但对于复杂病变行PCI,血管内超声(intravascular ultrasound,IVUS)优于CAG。IVUS证实左冠状动脉分成两个不对称的分支(即左前降支和左回旋支),管腔直径越来越小,近端主血管与其两个(或多个)远端分支直径的关系为:近端主血管=(远端主血管+侧分支)×0.67[2]。欧洲分叉俱乐部将分叉病变定义为发生在邻近和(或)涉及重要分支起源的冠状动脉狭窄[2]。左主干是冠状动脉最大的分支,为超
