RESUMO
Direct contrasting of the anterior epidural space with 9-10% verografin solution was conducted in 123 patients (120 with discogenic radiculitis, 2 with tumors, and 1 with injury to the spine). The epidural space was contrasted for a distance of 3-4 intervertebral spaces and no stimulation of the epidural structures occurred. The epidurograms demonstrated convincing information concerning the character of the protrusion and prolapse of the intervertebral discs and the existence of block of the epidural space in tumors. Phenomena of "spinal epilepsy" occurred in 5 cases, which regressed rapidly after a complex of measures was applied. Anterior epidurography with water-soluble contrast media of low concentration is an informative and safe method.
