DREZ surgery on conus medullaris (after failed implantation of vascular omental graft) for treating chronic pain due to spine (gunshot) injuries.
The results of DREZlesioning procedure used for the treatment of chronic intractable pain due to deafferentation caused by gunshot injuries at the thoracolumbar (T10-L1) spine level are reported in six patients. The specificity of these cases arises from the fact that all the patients underwent, after decompressive laminectomy, an implantation of vascularized omental graft on the injured cord segments, 4-17 months after injury. Because of the failure of this method, which did not improve spinal function nor hinder the development of pain, surgery in the DREZ was performed 2-5 years after implantation. The results of the microsurgical DREZotomy procedure in those patients, 7-12 months after the surgery were: 4 patients with complete pain relief and 2 patients with pain relieved of 80%. All the patients with well-confined segmental pain were completely cured.
