I saw the news report about the possible link between CCSVI and MS today on BBC news and then found the Sky news report on You Tube via the MS Society website. The definition of CCSVI is from Wikipedia.
Maybe this could be a breakthrough and a widening of the said veins could be an effective treatment for MS.
YouTube - BREAKING NEWS: MS Society comments on CCSVI announcement live on Sky News
Chronic cerebro-spinal venous insufficiency (CCSVI) is a recently proposed syndrome in which the cervical and thorac veins are not able to remove efficiently the blood from the central nervous system (CNS).
It is hypothesized to be due to stenosis of the jugular and azygos veins. Such a vascular picture has been described by Paolo Zamboni in 2008, who also reported an association of CCSVI with multiple sclerosis (MS). In a later double blinded study, a significative correlation was found between MS and CCSVI[1].
