Canada has one of the highest rates of MS in the world. Established treatments aren't reliably effective for patients with the disease. Thus, it's not surprising that there's been a lot of interest in chronic cerebro-spinal venous insufficiency (CCSVI) or blocked veins draining blood from the brain as a possible cause of MS. In 2008, Dr. Paolo Zamboni of Italy published a series of case reports of patients with MS treated with venous angioplasty. Since then, many patients have travelled abroad to receive the treatment. Recently, there have been reports of complications from the MS Zamboni treatment. I was interviewed on the program Skeptically Speaking. The fact I was a guest on that particular show doesn't make be a skeptic about the procedure. What I tried to do was summarize where we're at in what has been a very controversial medical news story. I invite your comments.
