It has been recently reported the possible presence of abnormalities in the cerebral venous circulation of people with MS, in healthy controls and in people with other neurological diseases. These reports have aroused much interest both in the scientific world and, above all, among the communities of patients and Associations having the aim of aiding people with MS and of promoting scientific research into this disease. In particular, the studies by Zamboni and colleagues (Ferrara University) and by Zivadinov and colleagues (University of Buffalo) have suggested an association between CCSVI and MS that was widely reported by the mass media world-wide.
