The European Society of neurosonology and cerebral hemodynamics (ESNCH) came out with a strong criticism of ultrasonographic criteria proposed by the brain hemodynamics community.
“…It is also unclear how it was decided that two or more of these five ultrasound criteria may be used to diagnose CCSVI, since no validation of these criteria was performed by different and independent observers nor were they blindly compared with a validated gold-standard investigation..”
What exactly are those criteria and who authored them? The ESNCH abstract does not say, but they are probably similar to the ones found in a Dutch article found in Phlebology  and even described in the Wikipedia entry 
“…It is still not clear whether magnetic resonance venography, venous angiography, or Doppler sonography should be considered the gold standard for the diagnosis of CCSVI…”
Your surgeon would then follow the jugular vein and attempt to improve the vein narrowing (stenosis) situation. This is often done by threading a balloon through the vein, as seen below
Naturally , even if MS would indeed by caused by CCSVI, the blood circulation could be multiple:
“…Most of the venous problems in MS patients have been reported to be truncular venous malformations, including azygous stenosis, defective jugular valves and jugular vein aneurysms. Problems with the innominate vein and superior vena cava have also been reported to contribute to CCSVI…”
I am not sure that all of these problems are amenable to the angioplasty type of procedure.
So CCSVI hopefuls beware, besides the inherent risks of CCSVI, the decision criteria as whether to have it or not is under debate.
