Chronic Cerebrospinal Venous Insufficiency
In 2008, Italian vascular surgeon Paolo Zamboni reported research suggesting that MS involves a vascular disease process he referred to as chronic cerebrospinal venous insufficiency (CCSVI, CCVI), in which veins from the brain are constricted. He found CCSVI in the majority of people with MS, performed a surgical procedure to correct it and claimed that 73% of people improved. Concern has been raised with Zamboni's research as it was neither blinded nor controlled and further studies have had variable results. This has raised serious objections to the hypothesis of CCSVI originating multiple sclerosis. The neurology community currently recommends not to use the proposed treatment unless its effectiveness is confirmed by controlled studies, the need for which has been recognized by the scientific bodies engaged in MS research.

Famous quotes containing the word chronic:
“What the horrors of war are, no one can imagine. They are not wounds and blood and fever, spotted and low, or dysentery, chronic and acute, cold and heat and famine. They are intoxication, drunken brutality, demoralisation and disorder on the part of the inferior ... jealousies, meanness, indifference, selfish brutality on the part of the superior.”
—Florence Nightingale (1820–1910)
