经桡动脉用7.5F无鞘指引导管完成冠状动脉复杂病变介入治疗的初步经验

Complex transradial percutaneous coronary intervention using sheathless guide catheter

目的总结北京友谊医院心血管病中心心内科使用无鞘指引导管(日本ASAHI)经桡动脉完成的60例冠状动脉复杂病变患者介入治疗的经验和体会。方法回顾分析患者的临床资料、影像资料以及术后恢复情况,对无鞘指引导管的使用特点进行总结分析。结果 60例患者均为复杂冠状动脉病变,其中,慢性完全闭塞病变(CTO)13例,迂曲合并钙化病变17例,左主干病变7例,分叉病变32例(包括左主干病变7例和同时合并CTO病变2例)。行经皮冠状动脉介入治疗(PCI),成功57例,失败3例,成功率95.0%。患者使用7.5 F的无鞘指引导管,均顺利通过桡动脉到位。左冠状动脉使用的无鞘指引导管型号依次为:JL3.5/4.0(44例),AL1.0(3例),SPB4.0/3.5(2例),PB4.0(2例);右冠状动脉:JR3.5/4.0(9例)。13例CTO病变使用的无鞘指引导管型号依次为:JL3.5/4.0(8例),PB4.0(2例),AL1.0(2例),JR4.0(1例);17例迂曲钙化病变:JL3.5/4.0(8例),JR3.5/4.0(6例),SPB3.5/4.0(2例),AL1.0(1例);32例分叉病变使用的无鞘指引导管型号均为JL3.5/4.0或JR3.5/4.0。结论经桡动脉使用7.5 F无鞘指引导管有良好的通过性,且导管管腔大、管壁厚、支撑力强,能胜任大多数分叉病变的双支架技术和对吻球囊技术,适合CTO、迂曲钙化病变等复杂病变的介入治疗。

Objective To summarizes the experiences and technique of complex transradial percutaneous coronary intervention （PCI） using sheathless guide catheter （Sheathless Eaucath, ASAHI） for 60 patients with coronary heart disease. Methods Retrospectively analyzed the data from 60 patients received PCI using sheathless guide catheter. Results PCI were performed on a total of 60 patients with complex lesions. Angiographic success was achieved in 95.0%and failed in three patients with CTO. 7 patients were with left main lesions, and 32 patients were with bifurcation lesions（including 7 patients with left main lesions and 2 patients with CTO）, and 13 patients were with CTO, and the other 17 patients were with tortuous and calcified lesions. Sheathless guide catheters of 7.5Fr were used for PCI in all patients, and all catheters successfully passed through the radial artery and were put in place. No other vascular complications associated with the use of the catheter occurred. Sheathless guide catheters were respectively JL（8 patients）, PB（2 patients）, AL（2 patients）, and JR（1 patient） in 13 patients with CTO, and were respectively JL（8 patients）, JR（6 patients）, SPB（2 patients）, AL（1 patient） in 17 patients with tortuous and calcified lesions. JL or JR were used in all 32 patients with bifurcation. Conclusions Use of the Sheathless of 7.5 Fr is safe and feasible, and allows complex interventions to be undertaken transradially with a high success rate.
