摘要(Abstract)：

目的　探讨旋切刀外径与病变特征对后退式旋切导管 (PAC)治疗冠状动脉病变即刻与近期疗效的影响。方法　 5 5例冠状动脉病变选用PAC导管治疗 ,其中 17例为支架内再狭窄病变 ,应用定量冠状动脉造影评价即刻和近期疗效。结果　 5 5例患者PAC导管的器械成功率为 95 % ,PAC导管最小管腔直径增益 (0 91± 0 5 9)mm ,主要并发症包括血管内膜撕裂 7例、完全闭塞 1例 ,6个月随访造影再狭窄率为 2 7%。使用 2 4mm导管较 2 0mm导管有较大的即刻血管内腔拓宽 ,随访时血管腔直径丢失较少 (但P >0 0 5 )。PAC导管对向心性病变较偏心性病变有更好的即刻效果 ,但 6个月再狭窄率相近 (2 4 %对 30 % ,P >0 0 5 )。结论　PAC导管直径、血管病变特征可能影响PAC导管即刻和近期疗效。
