[Cavo-spinal phlebography in myelopathies of venous origin. Application of the method in 115 cases].

The intraspinal venous stasis, described by ABOULKER as the cause of numerous myelopathies, is due to the addition of multiple venous abnormalities, demonstrated by cavospinal phlebography. The venae cavae and their major affluents and the prespinal system (lumbar and ascending lumbar veins, azygos, hemi-azygos, right superior intercostal and vertebral veins) are explored by catheterization. Cavo-spinal phlebography reveals multiple obstacles and the resulting stasis in the intraspinal plexus.
