Welcome to the forum! It is amazing how many "newbies" we have since August -- the word of CCSVI is spreading.
There actually are quite a few of us who have SPMS that have had the procedure. I think we felt a little more desperate than those with the mild symptoms. The SPMS people were going for no more progression - if there were improvements, than Hallelujah!
Is it possible I'll hear something like "oh, I'm sorry, we can't do this procedure on people that are as far advanced as you are."?
At this time, Dake is taking all types of MS'rs. He will remind you over and over, that he is not guaranteeing any improvement - he just does not know. I had my surgery the first of June --- at this point in time, I can tell you I have not had any progression in almost six months.
Hopefully, when Zamboni's new study results are published, we will have a better idea as to how patients fared over a two year period.
Be patient with Stanford - you will get a call,
