There is no consensus on CCSVI. It is a personal choice usually governed by your approach to risk and do you have sufficient funds to go with your choice.
I assess that balloon venoplasty is a low risk compared to progression of my MS. I have sufficient money to have had balloon venoplasty on two occasions (June 2010 and June 2011) worth it for me.
Consensus takes a long time to acheive.
