Technical dysfunctions have been reported reducing efficacy of deep brain stimulation (DBS). Here, we report on an essential-tremor patient in whom a short circuit in bipolar DBS resulted not only in unilateral loss of therapy but also in high current flow and thereby rapid decline of the impulse-generator battery voltage from 2.83 V a week before the event to 2.54 V, indicating the need for an impulse-generator replacement. Immediate re-programming restored therapeutic efficacy. Moreover, the reduction in current flow allowed the battery voltage to recover without immediate surgical intervention to 2.81 V a week later.
据报道，技术故障会降低深部脑刺激（DBS）的疗效。在此，我们报告一名特发性震颤患者，其双极DBS出现短路，不仅导致单侧治疗失效，还造成高电流，进而使脉冲发生器电池电压从事件发生前一周的2.83 V迅速降至2.54 V，这表明需要更换脉冲发生器。立即重新编程恢复了治疗效果。此外，电流的降低使电池电压得以恢复，无需立即进行手术干预，一周后恢复到2.81 V。
