should i really be not be afraid

There are risks as with any procedure however I am more afraid of the MS!

don't choose stents if you're worried, which you sound like you are, that's where there is some debate about safety and the need for a better stent to be developed.

ccsvi treatment that's just angioplasty is an outpatient procedure...minimal risk, lots to gain...in the ccsvi subforum, there is a sticky thread about angioplasty risks, probably you should start tehre!

Post this kind of question on the CCSVI topic - you'll get a lot more responses.
Just FYI - my wife had the procedure done 5 weeks ago, ballooning only, very simple and painless. She is seeing some improvements already.
