Selective spinal cordectomy: clinicopathological correlation.
The operation of selective spinal cordectomy is rarely performed. The cases of 10 paraplegic patients who underwent this procedure are presented. Their clinical indications were varied, including posttraumatic syringomyelia, uncontrollable leg spasticity, posttraumatic spontaneous neurogenic leg pain, and repair of a myelomeningocele gibbus. The cordectomy specimen was available for pathological examination in nine cases. Specimens removed from or near the site of spinal cord trauma showed extensive gliosis, leptomeningeal fibrosis, and schwannosis. This latter feature possibly represents an attempt at spinal cord repair by the dorsal root ganglion cells. Four specimens contained a syrinx with features including a thick gliotic wall and enlarged Virchow-Robin spaces, features that have been implicated in the pathogenesis of posttraumatic syringomyelia. Clinical results in the patients with syringomyelia and uncontrollable leg spasticity have been excellent. Cordectomy did not provide permanent relief in the patients with neurogenic leg pain. The authors conclude that selective spinal cordectomy is a valuable procedure for specific indications.
