摘要
目的 总结因保留导丝至起搏导线断裂的病例,观察保留导丝对起搏导线的影响 方法 观察了自2010年1月至2013年12月因导线断裂在南京鼓楼医院行导线拔除的患者6例,其中5例采用了保留导丝技术.结果 5例患者均成功拔除了导线.2根右心室主动固定导线的保留钢丝及导线内部线圈均断裂,断裂处在锁骨下静脉.2例左心室导线的保留导丝及导线线圈均断裂,断裂部位在三尖瓣环,1例左心室导线仅保留导丝断裂,但内部线圈仍完整,测试导线阻抗未见明显升高.结论 保留导丝可损伤导线绝缘层及内部线圈,建议慎用保留导丝技术.
Objective Observe the influence of retained guidewire on the pacing lead.Methods From Jan.2010 to Dec.2013,Nanjing Drum Tower Hospital,six patients received leads extraction because of lead fracture were enrolled in our study.Results Five patients had retained guidewire.All leads were extracted using mechanical tools,including 2 right ventricular fixed leads and 3 left ventricular pacing leads.Fracture of the coil electrodes as well as deterioration of the insulation coating was found in 4 patients.1 retained guide in left ventricular pacing fracture,but the pacing parameters,including impedance was not elevated.Conclusion The retained guidewire technique should not be used because delayed electrode damage can occur.
