Liberation therapy has been found by a Canadian study to be ineffective in aiding patients suffering from multiple sclerosis. A controversial treatment in its own right, the procedure opens veins in the neck to drain blood. The process has not been approved in Canada, however; surgeons in Eastern Europe, Latin America, and the United States still use it despite no tangible evidence that supports its effectiveness.
A team of researchers from the Vancouver Coastal Health and the University of British Columbia found that there was no difference in the 49 patients that underwent the treatment, which was called venoplasty, in comparison with the 55 that underwent a different version of this procedure. The unpublished results were released by researchers at the Society for Interventional Radiology in Washington.
The study states that there was no sign of any patient benefitting from the procedure within 72 hours of undergoing the procedure or within 48 weeks of having the venoplasty and the other treatment. This has confirmed Canada’s stance against not advocating the use of liberation therapy, and surgeons now hope that MS patients will not choose lifestyle changes and drug treatments, instead of deciding to get liberation therapy in other another country. This is because the procedure is dangerous for the patient and can cause damage to the veins or blood clotting.
There is new research ongoing on different treatments for multiple sclerosis, which is exciting news, especially the treatments involving stem cell. Liberation therapy became popular in 2009, when Paolo Zamboni, an vascular surgeon from Italy, suggested that narrowing the neck veins will allow iron to gather in the spinal cord and brain, which will result in an autoimmune response found in MS.
There are also numerous videos online about patients that under venoplasty and confirmed that the procedure caused improvements in their MS symptoms, but it was found in studies that after liberation treatment, patients may experience a temporary relieve from their MS symptoms.
