Well, yes, angioplasty is a procedure approved for certain conditions. To be precise, it is approved for the treatment of partial blockages in arteries. Read that carefully - approved for arteries. The V in CCSVI refers to veins.
As a procedure, it is usually performed my a consultant cardiologist, regardless of which artery is concerned. When I had an angiogram in 1999, there was a cardiologist standing by, ready to perform an angioplasty if I only had one arterial blockage. As things turned out, I had rather more than one blocked artery.
Using your logic, any treatment should be given to anyone who wants it, regardless of their actual condition. Follow this through to its logical conclusion, and you would approve of ECT being given to someone with an ingrowing toenail. Note, please, that ECT is not an approved treatment for ingrowing toenails. Now I am quite sure that you did not want to convey such an opinion, but you are arguing in favour of public money being used to pay for an unproven treatment.
As you know quite well, David, when I say “unproven treatment” I am referring to a procedure to expand a partially (or wholly) occluded vein as a treatment for MS. Note that this is not just my opinion. When Stanford University closed down its CCSVI operation, the following statement was made by Dr Jeffrey Dunn, Associate Director of the Stanford MS Center
“If I can do anything to protect MS patients from the potentially devastating effects of false hopes or the risks of invasive and unproven treatment, I am happy to do so”.
Now, If you want to debate “proven”, or “unproven”, in the context of the Popperian view of science in relation to the theories of (shall we say) Kuhn, or Lakatos, or Feyerabend, I will happily oblige. Until then, I submit that waiting for the results of even one of the pending Stage III trials is a far more responsible thing to do than arguing in favour of a treatment for which there is currently no valid evidence.
