摘要 目的 对复杂冠状动脉病变经皮冠状动脉介入治疗 (PCI)的成功率及影响因素进行初步探讨。方法 共观察复杂病变介入治疗 2 2 7例 ,处理靶血管 2 97支 ,靶病变 36 3处 ,对其临床资料、病变分布、病变特征进行分析。结果  2 2 7例共置入支架 34 9个 ,病例成功率为 97.4%,病变成功率为 96 .1%,残余狭窄率为 1.7%± 7.5 %;82处长弥漫性病变置入支架长度为 34 .8± 11.95mm ,其中两个以上支架相连接 46处 ;76例完全闭塞性病变中 ,71例顺利通过导丝和球囊预扩张后置入支架 ,病例成功率为 93.4%;6例左主干病变均成功置入支架 ,病例成功率为 10 0 %;5例左室射血分数 (EF) <30 %者在IABP辅助支持下完成手术。结论 复杂冠状动脉病变的PCI,在严格手术策略、选择适当手术器械、提高手术技巧和方法、充分估计利弊得失等诸因素前提下 ,完全可以提高复杂病变介入治疗的成功率。
