One study presented at the joint meeting of the European and Americas Committees for Treatment & Research in Multiple Sclerosis, found that eight of 15 children with pediatric MS had venous abnormalities when examined with magnetic resonance venography.
Another, conducted in 45 healthy controls and 133 adult MS patients, found signs of CCSVI in about half the patients -- but also in one-third of the controls.
The other studies all either failed to find CCSVI at all in their participant groups, or it was equally distributed between patients and controls.
The latter included one of the largest studies reported so far, with 160 MS patients and 160 healthy controls. Transcranial echo-color Doppler sonography indicated possible CCSVI in 16 patients, but venography found stenoses in only two patients.
The authors, from the University Hospital of Padova in Italy, declared in their poster that "CCSVI is definitely not the cause of MS."... Read More - http://www.msrc.co.uk/index.cfm/fuseact ... ageid/2944
