科学领域:

  • 神经外科 神经外科
  • 干预性神经放射学 干预性神经放射学
  • 血管神经学 血管神经学

背景情况:

  • 由于上内动脉 (ICA) 囊动脉瘤导致的下结节出血 (SAH) 需要有效的治疗.
  • 流量转移支架 (FD) 和卷轴是复杂动脉瘤的确立治疗方法.
  • 复发需要仔细考虑再处理策略.

研究的目的:

  • 在复发性ICA泡动脉瘤的神经干预治疗期间报告罕见的并发症.
  • 为了突出通过重叠的流量转移器支架网的远程线圈迁移的潜力.

主要方法:

  • 一名因破裂的ICA泡动脉瘤引起的SAH患者接受了FD和卷积的治疗.
  • 用第二个FD来管理复发,并通过后循环访问尝试PCOM卷轴.
  • 血管造影和神经干预技术用于诊断和治疗.

主要成果:

  • 最初的治疗是成功的,但通过后部通讯动脉 (PCOM) 发生了大量复发.
  • 在ICA中用第二个FD重新治疗并没有达到足够的动脉瘤静止.
  • 在PCOM卷轴过程中,一个远端卷轴末端通过两个重叠的FD的网格迁移到中脑动脉中.

结论:

  • 这一案例表明了之前未知的卷轴迁移并发症,通过在神经干预手术过程中重叠的FD.
  • 流量转移器支架的组成可能会导致这种类型的并发症.
  • 对于神经干预学家来说,意识到这种潜在问题至关重要.
