Microclip placement during AVM resection is generally accepted to be a safe practice in neurosurgery. Here, we describe an unusual complication involving cranio-spinal clip migration discovered five years after the initial AVM surgery.
A 53-year-old man underwent resection of a superior vermian AVM that required the placement of two microclips during the procedure. Five years after surgery, the patient suffered from descending sensory radiculopathy that resolved spontaneously. The workup revealed cranio-spinal migration of one of the previously placed microclips.
AVM clip migration is a rare phenomenon; however, the diagnosis should be entertained in patients with posterior fossa instrumentation who suffer from unusual neurologic symptoms.
在神经外科中，动静脉畸形切除术中使用微夹通常被认为是一种安全的做法。在这里，我们描述了一种五年后发现的涉及颅脊夹迁移的不寻常并发症。
一名 53 岁男性接受了上蚓部动静脉畸形切除术，手术中需要放置两个微夹。手术后五年，患者出现下降性感觉神经根病，自发性缓解。检查发现之前放置的一个微夹发生了颅脊迁移。
动静脉畸形夹迁移是一种罕见现象；然而，对于接受过颅后窝器械治疗且出现异常神经症状的患者，应考虑到这种诊断。
