【摘要】 目的 了解冠状动脉分叉处病变支架置入术对相关边支血管的影响。

    方法 60例病人，66处分叉病变使用PTCA和支架术治疗，观察介入治疗对分叉病变相关边支血管的影响。 结果 术中有12根边支血管受压迫，边支受累发生率为14.28%，以具有边支开口狭窄的Ⅰ型和Ⅳ型分叉病变的边支受累发生率为高。

    结论 冠状动脉分叉病变的介入治疗操作和分叉病变本身的解剖特征均是影响边支血流的重要因素。

    Intrcoronary stent for the bifurcational lesions-related side branch for patients with coronary heart disease Wo Yan Jilin Chinese-West Medical Hospital132012.

    【Abstract】 Objective To study the changes of bifurcational lesions related side branch during coronary inter-vention.Methods 60patients with66coronary stenosis lesions in bifurcation enrolled the study.Intracornary stents were developed in the lesions.The incidence of side branch compression were determind during percutaneous coronary intervention(PCI).Results 12side branch vessel were compressed during PCI(14.28%)，especiallyⅠandⅣtype bifurcation lesions.Conclusion The operation of PCI and anatomic feature of bifurcation lesions were the important factors that caused the side branch compression during PCI in bifurcation lesions. ......
