Deep brain stimulation (DBS) hardware complications, like electrode migration, are increasing. Securing connector placement can prevent recurrent lead issues and improve patient outcomes.

Area of Science:

  • Neurosurgery
  • Biomedical Engineering

Background:

  • Deep brain stimulation (DBS) is increasingly used for Parkinson's disease.
  • Hardware complications, including lead issues, necessitate frequent interventions.

Observation:

  • A patient with Parkinson's disease experienced electrode migration due to a malpositioned connector below the mastoid process.
  • Following revision, connector migration recurred from the parietal to the cervical region, causing further lead issues.

Findings:

  • Straining of extension leads is a critical warning sign for imminent electrode dislocation or lead fracture.
  • Connector placement below the mastoid or in the cervical region increases the risk of migration, especially with shorter extensions.

Implications:

  • Thorough analysis of DBS system failures is crucial to minimize morbidity.
  • Securing connector position during revision surgery can prevent recurrent dislocations and improve DBS therapy reliability.
