新型微孔射频系统对组织的消融效果和并发症研究

Study of New Micropore RF system on Lesion Formation and Complications

目的通过体外消融系统对新型微孔灌注消融导管的安全性和有效性研究,为临床实践提供参考依据。方法在相同的射频系统条件下同步研究两种导管在心脏组织消融深度、组织温度和血栓形成方面的情况。结果功率设置25 W时,两组消融深度比较无显著差异,均无Pop(组织内蒸汽爆裂)发生,无血栓形成;功率设置大于40 W时,两组发生Pop较多,并伴有血栓形成。结论在高功率消融参数下进行心脏射频消融手术,术者应密切关注其并发症和血栓形成情况。

Objective To study the safety and effectiveness of a new type of micropore ablation catheter in vitro ablation system, and to provide reference for clinical practice. Methods To evaluate two kinds of catheter in cardiac tissue ablation depth, tissue temperature and thrombosis situation by the same RF system. Results The power set 25 W, There was no significant difference in ablation depth between the two groups, and no Pop and thrombosis occurred. When the power is more than 40 W, two groups occurred more Pop and thrombosis. Conclusion When using high power for Cardiac RF ablation, doctors should pay more attention to complications and thrombosis.
