Area of Science:

  • Neurosurgery
  • Neurology
  • Epileptology

Background:

  • Invasive electroencephalography (EEG) using subdural electrodes is vital for localizing the epileptogenic zone in refractory epilepsy.
  • Subdural electrode implantation is a common preoperative neurosurgical procedure for epilepsy patients.
  • While effective, this invasive method carries a risk of rare but serious complications.

Purpose of the Study:

  • To systematically review the literature on safety issues and potential complications of subdural electrode implantation.
  • To identify and discuss strategies for avoiding complications associated with this neurosurgical procedure.
  • To enhance the early detection and prompt management of complications through comprehensive knowledge.

Main Methods:

  • Systematic literature review of studies reporting on subdural electrode implantation for epilepsy.
  • Analysis of safety data, including incidence, types, and severity of complications.
  • Compilation of reported complication avoidance and management strategies.

Main Results:

  • Complications, though rare, can be serious and include infection, hemorrhage, and neurological deficits.
  • Specific implantation techniques and patient selection can mitigate risks.
  • Early recognition and prompt intervention are key to managing adverse events.

Conclusions:

  • Subdural electrode implantation is a valuable tool in epilepsy surgery, but awareness of potential complications is critical.
  • Implementing established avoidance strategies and ensuring prompt management can improve patient safety.
  • Further research into minimizing risks and optimizing outcomes is warranted.
