This Is MS Multiple Sclerosis Community: Knowledge & Support

AAN makes it hard to link to their abstracts. This was a poster presentation. It can be accessed by going here http://aan.posterview.com/ and using veins as the search term. The first result is, "Multiple Sclerosis changes the apparent size of intralesional and extralesional parenchymal veins."

MS brain veins are significantly larger than those of healthy controls or other neurological disorders, except at the vein within the lesion, which is significantly narrower.

Would this be due to slowed flow due to CCSVI, resulting in congestion, resulting in larger parenchymal veins?

Should CCSVI research include before-and-after measurements of these brain veins? Perhaps treatment of CCSVI will result in a normalization of the size of parenchymal veins.

Dr. Zivadinov has previously presented research on the reduced parenchymal vascular architecture in patients with MS. Veins vanish... So perhaps the larger veins being found here are a result of the remaining veins taking on more flow to compensate for the veins that have vanished.
