C.T.-guided pain procedures.

C.T.-guided stereotactic destructive pain procedures; percutaneous cordotomy, trigeminal tractotomy-nucleotomy and extralemniscal myelotomy are presented. All procedures were applied in 32 cases without any mispuncture or complication. Advantages of C.T. guidance are direct visualization of target electrode relations, measurements of spinal cord diameters at the lesion site, and demonstration of spinal cord displacement during the procedure.
