Guidezilla ^(TM)导引延长导管在复杂冠状动脉病变中的初步应用经验

Preliminary application experience of Guidezilla^(TM)guide extension catheter during complex coronary percutaneous coronary intervention procedure

目的观察Guidezilla?导引延长导管在复杂冠状动脉病变行经皮冠状动脉介入治疗(PCI)中应用的安全性和有效性。方法 13例患者均为冠状动脉复杂病变,PCI术中球囊或支架难以送达靶病变时,应用Guidezilla?导引延长导管技术。结果 13例患者中慢性完全闭塞病变7例,钙化病变7例,迂曲病变6例,弥漫病变8例,远段病变8例,靶血管有支架置入史8例。13例患者手术均获成功,术后靶血管残余狭窄<20%,TIMI血流Ⅲ级。1例术中发生Guidezilla?导管嵌顿,于该处置入支架后改善。无血管夹层或破裂、急性支架内血栓、导丝所致的穿孔和心脏压塞等事件发生。结论 Guidezilla?导引延长导管用于复杂冠状动脉病变行PCI是安全、有效的。

Objective To evaluate the clinical safety and efficacy of Guidezilla？ guide extension catheter during complex coronary percutaneous coronary intervention（PCI）. Methods A total of 13 patients were included in the studywho presented with complex coronary lesions during PCI. Stents or balloons could not be delivered to these complex lesions with conventional approach and Guidezilla？ guide extension catheters were used. Results Among these 13 patients,there were 7 CTO lesions,7 calcified lesions,6 tortuous lesions,8 diffuse lesions,8 distal lesions and 8 lesions with pre-existing stents. PCI success rate was 100 %.In one patient,Guidezilla？ guide extension catheter was obstructed which were relieved after stent implantation. There was no major adverse cardiac event（MACE） during follow-up.Conclusions The Guidezilla？ guide extension catheter was safe and effective for PCI of complex coronary artery lesions.
