Transvenous pacemaker and defibrillator (PM-D) lead failure is an important clinical problem. Lead extraction is routinely performed in patients with transvenous pacemaker and defibrillator (PM-D) infections. The management of sterile PM-D leads that have failed or are no longer required is less uniform. While extraction of excess or failed sterile PM-D leads is often advocated, the risk of lead extraction must be weighed against the risk of abandoning these leads. There are no randomized trials comparing lead extraction with abandoning sterile leads in this setting. What then are the data that are used to advocate the extraction of excess or failed, sterile chronically implanted PM-D leads, and are the data adequate to make this recommendation?
经静脉起搏器和除颤器（PM-D）导线故障是一个重要的临床问题。在经静脉起搏器和除颤器（PM-D）感染的患者中，常规进行导线拔除。对于已经失效或不再需要的无菌 PM-D 导线，其管理方法并不统一。虽然通常提倡拔除多余或失效的无菌 PM-D 导线，但必须权衡拔除导线的风险与放弃这些导线的风险。在这种情况下，尚无比较拔除导线与放弃无菌导线的随机试验。那么，有哪些数据用于支持拔除多余或失效的无菌、慢性植入 PM-D 导线，这些数据是否足以做出这一推荐？
