科学领域:

  • 神经外科 神经外科
  • 神经学 神经学
  • 医疗器械 医疗器械

背景情况:

  • 腹腔中间核 (VIM) 是一种标准的深度大脑刺激 (DBS) 目标,用于基本震 (ET).
  • 新出现的证据表明,后部亚thalamic区域 (PSA) 可能提供优异的结果,但高层数据是有限的.

研究的目的:

  • 为了比较PSA DBS与VIM DBS在患有基本震的患者中的个体内疗效和副作用概况.
  • 评估两种刺激目标之间的减,生活质量和不良事件.

主要方法:

  • 一个随机,双盲,交叉试验,涉及双边DBS植入,针对VIM和PSA.
  • 在手术后,患者被分配到连续的VIM和PSA刺激期.
  • 主要终点是Fahn-Tolosa-Marin震动评分表 (FTM-TRS) 总得分的变化.

主要成果:

  • 在PSA DBS和VIM DBS (P = .328) 之间,整体震减少没有显著差异.
  • 在显著较低的刺激强度下,PSA DBS实现了临床益处.
  • PSA DBS在头部震 (P = .020) 和生活质量 (P = .046) 方面表现出优异的改善,言语和步态障碍较少.

结论:

  • 后部亚thalamic区域DBS可与VIM DBS相比,用于基本震中的震抑制.
  • PSA DBS在改善疾病特异性生活质量和潜在降低头部震方面具有优势.
  • 对于基本震管理,PSA DBS可能是一个更有效的目标,具有更好的副作用概况.
