[New method of draining a syringomyelitic cyst].

A new method of operative intervention for syringomyelia is described in which after the syringomyelia cyst is opened its permanent drainage is accomplished by introducing into its cavity the free end of an adjacent posterior root transected before-hand directly at the site of the funnel-shaped transition of the dura mater from the spinal cord onto the cuff. As a result, all movements of the spinal cord are made together with this root, which prevents the draining root from falling out of the cystic cavity and does not create conditions for it to inflict damage to the cystic walls and the surrounding cerebral tissue. The method was used in operations on 9 patients.
