Abstract		In the treatment of intractable pain, the neurosurgical procedures of coagulation lesions in the DREZ have proved most effective. The aim of the paper is to present technique of junctional microneurosurgical DREZ coagulation for treatment of pain syndromes with the help of bipolar coagulation electrode. 38 patients with intractable deafferentation pain were treated by surgery. Microsurgical technique was used for opening the subarachnoid space and exposing the spinal cord from the first normal rootlets above and below the injury or pain distribution at petipliery. Using a bipolar forceps, on tip of which the depth of penetration was marked (2-3 nun), a junctional coagulation lesion in the DREZ area was made. Tlie coagulation lesion extended along entire DREZ region of tle involved spinal cord segments. All the procedures included intraoperative neuromonitoring of the spinal cord evoked potentials. Technique of the functional microcoagulation in the DREZ region with the help of fine bipolar forceps alowed the operation without special equipment for temperature-controlled radiofrequency lesions or laser technology. With microneurosurgical skills the designed lesion in the DREZ was easy placed.
