title: [Cavo-spinal phlebography in myelopathies. Stenoses of internal jugular and azygos veins, venous compressions and thromboses].
abstract: Increased intraspinal venous pressure, resulting according to ABOULKER in numerous spastic paraplegias and quadriplegias is due to multiple venous abnormalities demonstrated by cavo-spinal phlebography. The most frequent are stenoses of the internal jugular veins, the left renal, the left iliac veins, the azygos veins and compressions of the innominate venous trunks. These abnormalities cause a permanent stasis in the intraspinal plexuses through excessive supply or insufficient drainage. Out of 80 patients, 60 per cent had at least 2 abnormalities, 38 per cent at least 3 abnormalities.
