Thanks, cheer, for arming us with some facts - always helpful! Perhaps the ISNVD will come up with a generally recognized, scientifically accurate name for this procedure - I hope so. I too don't like the "Liberation treatment" moniker for the reasons expressed above. For now, I just usually call it CCSVI treatment, and explain it to lay people as similar to angioplasty, which most have heard of.
If it came down to a patient vote (which I doubt it will!), I'd probably go with Interrupted's Cerebro-Spinal Venoplasty, or CSV for short.
