Multiple sclerosis: liberation procedure

I saw Dr. Paul Hébert on Global National talking about Zamboni’s work1,2 as dilating veins in the brain. This is false: angioplasty is done on the jugular veins in the neck and the azygos vein in the chest. How do I know? Because I had this done in Poland a month ago. The next time someone talks about a medical procedure, perhaps he or she should have the facts straight first.
