Paolo Zamboni (born 25 March 1957, Ferrara, Italy) is an Italian doctor who claims to have found in an unblinded preliminary study that in over 90% of the participants with multiple sclerosis there were problems in veins draining their brain, like stenosis or defective valves.[1] He also noticed high level of accumulation of iron deposits in the brain, supposedly due to restricted outflow of blood.[2]

According to Zamboni some symptoms of multiple sclerosis in his own wife as well as 73% of his patients abated after an endovascular procedure to open these veins.[3][4][5]

Zamboni named this condition chronic cerebrospinal venous insufficiency (CCSVI).[6]

The theory is controversial. The National Multiple Sclerosis Society has said that, while "there is not yet enough evidence to conclude that obstruction of veins causes MS," that "[Zamboni's] hypothesis on CCSVI and its corrective treatment is a path that must be more fully explored and one that we are supporting with research funding."[7] Since 2010, there has been more research that disputes the Zamboni theory.[8][9] According to a recent research carried out at the Cardiovascular Diseases Section, Department of Emergency and Organ Transplantation (DETO), University of Bari (Italy), venous echo-color-Doppler (ECD) showed that chronic cerebrospinal venous insufficiency (CCSVI) syndrome is related to multiple sclerosis (MS).
