摘要
目的 了解支架置入术对冠状动脉分叉处病变相关分支的影响。方法 12 0例病人 ,132处分叉病变使用经皮腔内冠状动脉成形术 (PTCA)和支架术治疗 ,观察介入治疗对分叉病变相关分支的影响。结果 术中有 2 4根分支血管受压迫 ,分支受累发生率为 14 2 8%。以具有分支开口狭窄的Ⅰ型和Ⅳ型分叉病变的分支受累发生率为高。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分支血流的重要因素。
Objective To study the effect of intracoronary stenting for bifurcational lesions on the related side branches. Methods One hundren and twenty patients with 132 coronary bifurcational lesions were enrolled in the study. Intracornary stents were deployed in the lesions. The incidence of side branch oppression was analysed. Results Twenty-four side branches were oppressed during PCI (14.28%), especially in type Ⅰ and type Ⅳ bifurcation lesions. Conclusion The details of PCI and morphotogical characteristics of bifurcation lesions were the important factors leading the side branch oppression during PCI in bifurcation lesions.
