The Telectronics Accufix Atrial "J" pacing lead poses a mechanical risk to patients of retention wire fracture and protrusion. Standard lead extraction techniques include percutaneous approaches, which are associated with significant risk of morbidity and mortality, and open procedures, which necessitate thoracotomy. In nine patients referred with Class III retention wire fractures, attempts were made to snare the protruding retention wire from a femoral approach using snare devices and bioptomes. In six cases, the retention wire was successfully removed, leaving the lead body in place. In four patients with lead function that was able to be evaluated, the atrial lead remained functional after the procedure. There were no complications. Snare removal of the protruding retention wire via a femoral approach should be considered as an option in the management of patients with Class III Accufix leads.
泰莱克电子Accufix心房“J”形起搏导线对患者存在固定导线断裂和突出的机械风险。标准的导线拔除技术包括经皮方法，这与显著的发病和死亡风险相关，以及开放手术，这需要开胸。在9例因Ⅲ类固定导线断裂前来就诊的患者中，尝试使用圈套器和活检钳经股动脉途径圈套突出的固定导线。6例患者成功取出固定导线，导线主体留在原位。在4例能够评估导线功能的患者中，术后心房导线仍保持功能。无并发症发生。对于Ⅲ类Accufix导线患者的管理，应考虑经股动脉途径圈套取出突出的固定导线这一选择。
