目的：评价管腔扩张导管（Corsair 微导管）联合新型慢性闭塞病变专用导丝在冠状动脉慢性完全闭塞（chronic total occlusion, CTO）病变介入治疗中的有效性与安全性。方法选择2011年12月至2013年8月应用Corsair 微导管联合新型CTO病变专用导丝处理CTO病变的89例患者为Corsair 微导管组（A组），以Corsair 微导管应用前的89例CTO病变患者为对照组（B组），记录两组患者的临床特征、冠状动脉造影所见病变特点、介入操作成功率和并发症发生率，随访术后主要不良心脏事件的发生率。结果 Corsair微导管组患者病变成功完成支架置入81例，操作成功率为91.0％，而对照组操作成功62例，操作成功率为69.7％，两组比较差异有统计学意义（P＜0.05）。Corsair微导管组造影时间及操作时间、对比剂用量均较对照组减少，术中术后无严重并发症，无死亡。结论 Corsair微导管联合新型CTO病变专用导丝用于经皮冠状动脉介入治疗CTO病变可以提高介入操作成功率。

Objective To assess the efficacy and safety of using a novel channel dilator (the Corsair microcatheter) accompanied with special occlusion guide wires for coronary chronic total occlusion (CTO) recanalization. Methods From 2011 December to 2013 August,we performed 89 cases (the study group) using channel dilator and the new special occlusion guide wires for CTO recanalization. Another 89 CTO lesions treated before using the corsair microcatheter were compared as the control group.We recorded clinical characteristic, outcome of PCI,radiation exposure time, contrast utilization and the procedure time. The MACE rate was monitored during follow up. Results The intracoronary channel dilator accompanied with special occlusion guide wires were inserted into 33 left anterior descending arteries, 17 left circumlfex arteries and 38 right coronary arteries. The success rates of procedure were signiifcantly higher in the study group than in the control group (91% vs. 67.7%, P < 0.05). Procedure and lfuoroscopy time tended to be lower in the study group than in the control group. There were no serious complications related to the catheter and no death case recorded. Conclusions The channel dilator accompanied with special occlusion guide wires may facilitate the conventional approach with a higher success rate in PCI.
