[Intraspinal venous hypertension due to multiple anomalies in the caval system. A major cause of myelopathies].
Increased venous intraspinal pressure is described as a venous system disease, resulting in numerous unexplained paraplegias and tetraplegias. The chronic venous stasis in the intraspinal plexuses, into which the circulation of the spinal cord is drained, is due to the association of multiple abnormalities (stenoses, compressions, thromboses) on the major pathways of the caval and azygos system. The abnormalities, most of which are not known, are demonstrated by a special procedure, the cavo-spinal phlebography, and some of them are subjected to surgery.
