Thermocoagulation of the dorsal root entry zone for the treatment of intractable pain.
The authors report the results of DREZ thermocoagulation in 35 patients since March 1980. This technique was applied not only in patients with deafferentation pain after brachial plexus avulsion, but also for postamputation phantom limb pain and pain caused by injury to the spine and spinal cord, by peripheral nerve lesions, and by multiple sclerosis. Independent of etiology, the duration of the pain syndrome, and the quality and projection of the pain, the overall results have been satisfactory and long-lasting.
