Since its introduction, the subcutaneous implantable cardioverter-defibrillator (S-ICD) has provided the benefit of reduced mortality from ventricular tachyarrythmias without the associated short- and long-term morbidity of transvenous or epicardial implantable cardioverter-defibrillator (ICD) leads. As its name implies, the S-ICD system is implanted in its entirety, including device and lead, just under the skin beginning along the anterior axillary line, with its lead tunneled to the left parasternum and then from the xiphoid to the manubrium-sternal junction. Dislocation of the lead due to migration of the parasternal lead has been described in a minority of patients. Here, we describe an unusual case of a significant lead migration in a pediatric patient.
自皮下植入式心脏复律除颤器（S-ICD）问世以来，它降低了室性心律失常导致的死亡率，且没有经静脉或心外膜植入式心脏复律除颤器（ICD）导线相关的短期和长期发病率。顾名思义，S-ICD系统包括设备和导线在内整体植入皮下，从腋窝前线开始，导线经隧道通向左侧胸骨旁，然后从剑突到胸骨柄-胸骨交界处。少数患者中曾有胸骨旁导线移位导致导线脱位的报道。在此，我们描述一例小儿患者导线严重移位的罕见病例。
