A patient implanted with the evoke spinal cord stimulation (scs) system reported pain at the midline incision.X-rays confirmed lead migration.Therapy remained adequate; however, the migrated lead bunched beneath the skin, causing significant discomfort.A lead revision was completed, and the midline incision site pain was substantially reduced, though post-operative pain persisted.

The lead was not returned to saluda.The x-rays provided are consistent with lead migration.The root cause of the lead migration and pocket pain could not be definitively determined.The evoke scs system surgical guide identifies potential risks associated with surgery and spinal cord stimulation, including ¿lead migration or suboptimal placement, which may result in undesirable stimulation changes,¿ and states that ¿the patient may require surgery, including revision, explant, or replacement,¿ as a result.(b)(4).
