[Changes in the somatosensory evoked potentials of patients with complicated spinal trauma after an omentomyelopexy operation].

The purpose of the study was to record somatosensory evoked potentials (SSEP) to objectify the results omentomyelopexy in late spinal cord injury. SSEP were recorded in 25 patients in leads of three levels of the somatosensory tract (from the popliteal fossa, from the lumbar enlargement of the spinal cord, and from the surface of the skull in the region of projection of leg presentation in cerebral hemispherical cortex) before and after surgery. The study indicated that there were no pre- or postoperative records of cortical evoked potentials. At the same time there was improvement in the magnitude of SSEP at the level of the lumbar enlargement (36%). In 4 (16%) and 5 (20%) cases of them SSEP changes were clear and unclear, respectively. The assessment of SSEP changes requires consideration of cases with unclear SSEP. Comparison of the results with clinical findings shows a correlation mainly with urological and urodynamic evidence. Thus, there are minor positive changes in the magnitude of SSEP after omentomyelopexy in the lumbar enlargement lead with unclearly pronounced evoked potentials.
