  • Title: Follow-up 26 years after dorsal root entry zone thermocoagulation for brachial plexus avulsion and phantom limb pain.
    Author: Tomycz ND, Moossy JJ.
    Journal: J Neurosurg; 2011 Jan; 114(1):196-9. PubMed ID: 20509732.
    Abstract:
    Brachial plexus avulsion and limb amputation are often associated with intractable chronic pain. Dorsal root entry zone (DREZ) thermocoagulation is an effective surgical treatment for upper-extremity deafferentation pain. The authors describe the clinical follow-up and imaging in a patient who underwent DREZ thermocoagulation 26 years ago for postamputation phantom limb syndrome with associated brachial plexus avulsion. This patient continues to have successful pain control without phantom limb sensation and has never experienced a recurrence of his left upper-extremity pain syndrome. This report lends credibility to the notion that, among ablative neurosurgical pain operations, DREZ thermocoagulation may provide the greatest durability of pain control.
