摘　　要：目的评价冠状动脉(冠脉)慢性完全闭塞病变(CTO)特点对经皮冠状动脉介入治疗(PCI)的影响。方法对300例CTO患者的临床资料、病变特征和PCI结果进行回顾性分析。结果闭塞病变类型为功能性及绝对性、长度≤15mm和>15mm、有开口和无开口及断端为鼠尾状和刀切状,以上各组内PCI成功率分别为90.1%和76.3%、85.2%和72.1%、88.3%和80%、84.2%和55%(P<0.05);闭塞病变的位置、闭塞时间、有无桥血管、有无分支发出、有无钙化、远端有无显影及血管有无迂曲各组内差异无统计学意义(P>0.05)。结论闭塞病变类型、长度、有无开口及断端的形状是成功PCI的影响因素。Objective To evaluate the influence of total occlusion coronary character to percutanenous coronary intervention. Methods Clinical and coronary angiographic data of 300 patients with Chronic total occlusion （CTO） who underwent Percutaneous coronary intervention （PCI） were retrospectively analyzed. Results Chi - square test revealed that a stump morphology, length of occlusion, ostial location and type of occlution were statistically signi ？ c - ant to PCI success （P 〈 0.05）. Conclusions Type of occlusion, length of occlusion, ostial location and tapered morphology are factors on successful PCI.
