Deep Brain Stimulation (DBS) surgery for movement disorders like Parkinson's disease carries risks. While most complications were temporary, thorough informed consent is crucial for patients undergoing DBS implants.

Area of Science:

  • Neurosurgery
  • Neurology
  • Medical Device Technology

Background:

  • Deep Brain Stimulation (DBS) is a neurosurgical intervention for movement disorders.
  • Technological advancements have aimed to minimize complications associated with DBS implants.
  • Despite improvements, DBS surgery remains associated with potential transient and permanent complications.

Purpose of the Study:

  • To report the complication rates and outcomes of Deep Brain Stimulation (DBS) surgery.
  • To analyze the types and frequency of adverse events in patients undergoing DBS.
  • To evaluate the safety profile of DBS in treating Parkinson's disease, essential tremor, and dystonia.

Main Methods:

  • Retrospective analysis of 86 patients who underwent 149 DBS implants.

  • Categorization of complications into perioperative, postoperative, hardware-related, and stimulation-induced side effects.
  • Assessment of patient outcomes and sustained neurological sequelae.

    • Main Results:

    • A total of 26 out of 86 patients (30%) experienced an untoward event during the procedure.
    • Complications included 8 perioperative, 8 postoperative, 9 hardware-related, and 4 stimulation-induced side effects.
    • Only 5 patients (6%) sustained persistent neurological sequelae; no fatalities or permanent severe disabilities were reported.

    Conclusions:

    • Deep Brain Stimulation (DBS) surgery, while effective, presents a notable risk of complications, with a significant percentage of patients experiencing adverse events.
    • The majority of complications were transient, with a low rate of persistent neurological sequelae.
    • Enhanced informed consent discussions are essential to fully apprise patients of all potential risks associated with DBS implantation.
