Research from the 1970s on spinal venous hypertension and myelopathies
June 3, 2011 at 10:09pm
Thanks to Mylène Therrien for the following info on research from the 1970s on myelopathy of the spine due to venous hypertension and malformations in the veins surrounding the spine. The 80 patients tested and treated in these studies had paraplegia and injury of the spine due to venous malformations.
They were treated for venous stenosis in the 1970s. Dr. Zamboni has referenced this research in his publications, but I hadn't seen these abstracts or understood the history.
Here are the abstracts and links I found from the info given in Mylene's posting:

Abstract
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.

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.
