Damaged insulation mimicked symptoms of occipital stimulator lead migration.


Journal Article

INTRODUCTION: The use of occipital nerve stimulators for the treatment of migraines has recently been suggested. However, there have been reports of complications, including lead migration causing local muscle stimulation and spasm with local burning sensation and loss of successful neuromodulation. CASE: We report a case of a patient who had successful permanent implantation and then presented with suspicion of lead migration. Upon examination of the lead at time of repositioning it was found that the insulation had eroded and the conducting wires exposed at the anchor site. DISCUSSION: Disruption of occipital nerve stimulator lead insulation may mimic lead migration with failure of neuromodulation, spasm, and local burning sensations. Prior to reimplanting, a lead should be thoroughly inspected to ensure there is no mechanical failure. Anchoring should be performed with gentle direct suturing or the use of a protective anchoring device.
