AI Article Synopsis
- Vagal neuropathy can occur after the placement of a vagal nerve stimulator (VNS), leading to vocal fold palsy, which is rare.
- A case is highlighted where delayed nerve compression from the VNS coil caused progressive hoarseness and vocal cord paralysis.
- To address the issue, coil removal and nerve decompression were performed, and larger coils were used for ongoing treatment to minimize the risk of similar complications in the future.
Article 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.
