新型锁定钢丝拔除心律植入电极导线的初步临床应用

Preliminary Clinical Application of a Novel Locking Stylet in Cardiac Lead Extraction

目的:探讨运用导线锁定钢丝(lead locking device,LLD)这种新型全程锁定钢丝系统拔除心律植入装置电极导线的安全性和有效性。方法:回顾中国医学科学院阜外医院利用LLD拔除电极导线的6例患者资料,总结分析电极导线拔除原因、锁定钢丝锁定导线情况、电极导线拔除结果、手术相关并发症等。结果:6例患者(其中1例女性,中位年龄62.5岁)使用LLD拔除电极导线,共拔除导线13根(1根废弃电极导线和12根有功能电极导线),其中LLD成功放置在11根(85%)电极导线的顶端进行全程锁定,2根(15%)未全程锁定。12根(92%)电极导线完全拔除,1根(8%)部分拔除,无严重并发症发生。结论:LLD这种新型锁定钢丝系统拔除电极导线安全、有效,有利于导线完全拔除。

Objective： To explore the safety and efficacy of a novel lead locking device （LLD） in the procedure of cardiac lead extraction for heart rhythm implants. Methods： A total of 6 patients using LLD for cardiac lead extraction in our hospital were retrospectively reviewed. Clinical parameters, the reason of cardiac lead extraction, lead locking stylet condition, outcome of lead extraction and operative complications were summarized. Results： There were 6 patients including 1 female with the median age at 62.5 years. LLD was used and 13 cardiac leads were extracted including 1 scrap electrode wire and 12 functional electrode wire. Among those, LLD was successfully inserted and locked on the top of 11/13 （85%） leads for whole procedure and 2 （15%） leads were not locked for whole procedure; 12 （92 %） leads were completely removed and 1 （8%） lead was partially removed. No severe complications occurred. Conclusion： The novel LLD may safely and effectively extract electrode lead which is beneficial for complete cardiac lead extraction.
