Researcher's labour of love leads to MS breakthrough
http://www.theglobeandmail.com/news/nat ... le1372414/Fighting for his wife's health, Dr. Zamboni looked for answers in the medical literature. He found repeated references, dating back a century, to excess iron as a possible cause of MS. The heavy metal can cause inflammation and cell death, hallmarks of the disease. The vascular surgeon was intrigued – coincidentally, he had been researching how iron buildup damages blood vessels in the legs, and wondered if there could be a similar problem in the blood vessels of the brain.
Using ultrasound to examine the vessels leading in and out of the brain, Dr. Zamboni made a startling find: In more than 90 per cent of people with multiple sclerosis, including his spouse, the veins draining blood from the brain were malformed or blocked. In people without MS, they were not.
More striking still was that, when Dr. Zamboni performed a simple operation to unclog veins and get blood flowing normally again, many of the symptoms of MS disappeared. The procedure is similar to angioplasty, in which a catheter is threaded into the groin and up into the arteries, where a balloon is inflated to clear the blockages. His wife, who had the surgery three years ago, has not had an attack since.
