Twiddler syndrome is uncommon in children and most commonly described as causing lead retraction with implanted cardiac pacemakers and defibrillators. We report an uncommon case of a child repeatedly "twiddling" a vagal nerve stimulator to the point of lead fracture. The findings of Twiddler syndrome illustrated here apply to all implanted devices and show the complication of lead fracture in addition to the more commonly reported complication of lead retraction. This case highlights the need to be aware of the radiographic findings of this phenomenon in children with implanted vagal nerve stimulators due to the perceived increased risk of "twiddling" in pediatric and developmentally delayed patients.
Twiddler 综合征在儿童中较为少见，主要表现为心脏起搏器和除颤器的导联回缩。我们报告了一例罕见的儿童反复“扭动”迷走神经刺激器导致导联断裂的病例。这里展示的 Twiddler 综合征的发现适用于所有植入设备，并显示了除更常见的导联回缩并发症外，还有导联断裂的并发症。这个病例强调了由于儿科和发育迟缓患者中“扭动”的风险增加，需要注意植入迷走神经刺激器的儿童中这种现象的影像学表现。
