Abstract：
Vagal neuropathy causing vocal fold palsy is an uncommon complication of vagal nerve stimulator (VNS) placement. It may be associated with intraoperative nerve injury or with device stimulation. Here we present the first case of delayed, compressive vagal neuropathy associated with VNS coil placement which presented with progressive hoarseness and vocal cord paralysis. Coil removal and vagal neurolysis was performed to relieve the compression. Larger 3 mm VNS coils were placed for continuation of therapy. Coils with a larger inner diameter should be employed where possible to prevent this complication. The frequency of VNS-associated vagal nerve compression may warrant further investigation.
摘要：
引起声带麻痹的迷走神经病变是迷走神经刺激器（VNS）放置的罕见并发症。它可能与术中神经损伤或装置刺激有关。这里我们介绍第一个延迟的情况，与VNS线圈放置相关的压缩性迷走神经病变，表现为进行性声音嘶哑和声带麻痹。进行线圈去除和迷走神经溶解以减轻压迫。放置较大的3mmVNS线圈以继续治疗。在可能的情况下,应采用具有较大内径的线圈以防止这种复杂性。VNS相关迷走神经压迫的频率可能需要进一步研究。
