Fielder XT导丝在功能性慢性完全闭塞病变中的应用

Clinical application of Fielder XT wire in percutaneous coronary intervention for functional chronic total occlusion

目的：总结FielderXT导丝在功能性慢性完全闭塞（CTO）病变介入治疗中的使用体会和经验。方法：回顾分析我科2011年1月～2012年10月住院使用过Fielder XT导丝行介入治疗的CTO病变患者的影像资料。根据CTO病变的影像特点将患者分为绝对性CTO病变组和功能性CTO病变组，分别统计上述两组的CTO病变经皮冠状动脉介入治疗（PCI）成功率，统计两组的Fielder XT导丝的CTO病变通过率，并进行比较分析。结果：功能性CTO病变组和绝对性CTO病变组CTO病变的成功率分别为89％、60％（40／45、22／37，P〈0.01）；两组FielderXT导丝的通过率分别为：71％、24％（32／45、9／37，P〈0.01）。结论：Fielder XT在功能性CTO病变中有较高的导丝通过率。

AIM： To summarize the application experience of percutaneous coronary intervention （PCI） using Fielder XT wire in treating patients with functional chronic total occlusion （CTO） lesion. METHODS： Data were retrospectively analyzed in patients with CTO who were treated by PCI using Fielder XT wire between January 2011 and October 2012. The success rates of PCI for CTO and the success rates of Fielder XT passing through CTO were, respectively, calculated in patients with functional CTO and with true CTO. RESULTS ： The success rates of PCI for functional CTO and for true CTO were, respectively, 88.9% vs. 59.5% （40/45, 22/37, P 〈0.01） and the success rates of Fielder XT passing through CTO were, respectively, 71.1% vs. 24.3% （32/45, 9/37, P 〈0.01）. CONCLUSION： The success rate of Fielder XT in passing through functional CTO is higher than in passing through true CTO. Fielder XT may be the preferred guide wire for functional CTO lesion.
