[Myelopathies in impairment of extravertebral venous blood circulation].
Development of myelopathies of venous genesis is based on venous hypertension inside vertebral canal which was initially described by J. Aboulker. According to anatomical and functional features of epidural venous system, two factors contribute in development of venous congestion: decreased outflow and increased inflow. Clinical manifestation is presented by spastic movement disorders. Morphological study performed in 18 cadavers allowed to discover so called 'narrow areas' which cause impaired circulation through large feeders of caval veins, which can be discovered by selective phlebography. Main phlebographic features include stenosis, compression, atresia, thrombosis and retrograde flow towards epidural venous plexus. We examined 58 patients with spastic para- and tetraparesis of unknown nature. Phlebographic signs of venous dyscirculation were revealed in 34 cases. 28 surgical operations were performed: 24 on feeders of vena cava superior and 4 on feeders of vena cava inferior. In 18 cases we obtained satisfactory results. This investigation should be continued.
