Dr. Paolo Zamboni, an Italian doctor who pioneered the liberation therapy shared that people with multiple sclerosis should be able to have surgery on blocked neck veins as a part of a clinical trial. He shared his opinions with MPs on the House of Commons health committee and revealed that the formula has resulted in better cognitive and motor function among people with multiple sclerosis, who were treated with balloons to open up the blocked neck veins.

He calls the condition "chronic cerebrospinal venous insufficiency," or CCSVI. Blood moves back into the brain and spine due to narrowed or blocked veins, which can cause damage that is akin to symptoms shown by some MS patients.

In order to know that whether there is a link between blocked veins and MS, the MS Society of Canada is spending $700,000 on four studies, before it will support any kind of surgical treatment. Spokeswoman, Karen Lee shared that the society wants that more people should be assessed for blockages that are impartially evaluated by doctors.

Dr. Robert Maggisano, a vascular surgeon at Sunnybrook Health Sciences Centre in Toronto added that people who undergo vein treatment are needed in the research to see whether they improve.

Maggisano said, “We're wasting time and money, and certainly not helping our people, who are going overseas to get treatment, when we should be able to do the studies in a blinded fashion within Canada”.
