Guidezilla延长导管在复杂冠脉病变介入治疗中的安全性和有效性

Safety and Efficacy of Guidezilla Extension Catheter for Treatment of Complex Coronary Interventions

【目的】探讨Guidezilla延长导管在复杂冠状动脉病变介入治疗中的安全性和有效性。【方法】回顾性分析深圳市孙逸仙心血管医院2015年8月至2017年9月间复杂冠脉病变采用Guidezilla延长导管辅助进行经皮冠状动脉介入治疗(PCI)的72例患者,观察手术成功率和并发症发生率,随访术后主要心脏不良事件发生率。【结果】71例(98.6%)经Guidezilla延长导管辅助下成功冠脉支架植入,1例支架脱载。慢性闭塞病变(CTO)4例,钙化病变44例,迂曲病变30例,严重成角病变15例。65例(90.3%)经桡动脉途径,7例经股动脉途径。术中术后无严重并发症,无死亡病例。术后1个月随访无不良心脏事件发生。【结论】对于介入治疗复杂冠脉病变,采用Guidezilla延长导管辅助介入治疗安全有效。

【Objective】To evaluate the safety and efficacy of Guidezilla extension catheter of complex coronary intervention.【Methods】This was a retrospective study and 72 patients with complex coronary artery diseases were enrolled during August of 2015 to September of 2017.The Guidezilla extending catheter was used during percutaneous coronary intervention(PCI)and the successful rate and the incidence of complications were recorded.In addition,the adverse cardiovascular events were also recorded during follow-up.【Results】The overall successful rate of PCI with the Guidezilla extending catheter was 98.6%.One case was failure due to the stent was stripped off its balloon.None of the patients experienced coronary dissection,perforation,air embolism,pressure dampening or other major complications during the procedure.Among these cases,there were 4 chronic total occlusion lesions,44 calcified lesions and 30 tortuous lesions.Sixty five cases were performed by radial access.After 1 month’s follow-up,none of the patients had any adverse cardiovascular events occurred.【Conclusion】During PCI procedure,the application of Guidezilla extension catheter for the treatment of complex coronary anatomy appeared safe and efficacious.
