Deep brain stimulation for intractable pain: a 15-year experience

Area of Science:

• Neurosurgery
• Pain Management
• Neurology

Background:

• Chronic pain syndromes significantly impact quality of life.
• Deep brain stimulation (DBS) is an option for refractory pain.
• Long-term outcomes of DBS for chronic pain require further clarification.

Purpose of the Study:

• To analyze long-term outcomes of deep brain stimulation (DBS) in chronic pain patients.
• To identify patient selection criteria for successful DBS treatment.

Main Methods:

• Prospective follow-up of 68 patients with chronic pain syndromes over 15 years.
• DBS electrode implantation in periventricular gray matter, thalamic nuclei, or internal capsule.
• Pain evaluation using a modified visual analog scale during 6-monthly follow-ups.

Main Results:

• Effective pain control (62%) achieved in 42 of 68 patients.
• Long-term follow-up averaged 78 months.
• Successful outcomes observed in failed back syndrome, trigeminal neuropathy, and peripheral neuropathy patients.
• Poorer outcomes noted in thalamic pain, spinal cord injury, and postherpetic neuralgia patients.

Conclusions:

• Deep brain stimulation (DBS) provides long-term pain relief in carefully selected patients.
• DBS is associated with minimal side effects and complications.
• Patient selection is crucial for optimizing DBS outcomes in chronic pain management.
