[Selective epidural phlebography in the diagnosis of tumors of the cervical spinal cord and of the cauda equina roots].

The method of selective epidural phlebography (SEP) was applied in the diagnosis of tumors of the cervical segment of the spinal cord and the roots of cauda equina in 45 patients. The diagnosis was confirmed in 32 of the 37 patients who were operated on. The SEP method does not produce serious complications and allows circulatory disorders in the vertebral venous plexuses to be revealed. The diagnostic value of the method is higher in tumors of superocervical localization and hourglass tumors.
