I always thought that Doppler < MRV < Venogram, when it comes to detection tools.
According to this study, having a venous malformation and abnormal cranial drainage is not clinically relevant for MS because the same thing is as prevalent in the general population.
What makes things even more confusing to me was that Zamboni's initial findings, which really started the CCSVI mania, were found using doppler. Yet now everyone is trying to invalidate this study by saying that doppler is not an accurate means of identifying CCSVI???
I think that some people may have stronger veins (more Vit D during their childhood/ their mother metabolised more sun during pregnancy?), veins that are less susceptible to microbleedings. so, maybe, some people will also have stenoses but do not develop MS for that reason.
Is this something that has been proven or is it a wild guess?
in any event, those with the weaker veins and MS benefit from liberation. that is the ultimate test! not whether other people happen to have stenoses and no MS.
Once again can you please let me know where you discovered that "those with weaker veins and MS benefit from liberation" Although there are some blinded studies in the woodworks, no one can make an ABSOLUTE claim about anything at this point.
No what made Zamboni's findings interesting was the fact that after people had angioplasty, their symptoms improved or abated significantly, some permanently. Who cares if it's diagnosed by Doppler, MRV, a dog sniffing you ... whatever. The results are important not the diagnostic. IF 100% of persons with MS have CCSVI (can someone show me where anyone hasn't YET? - and really I mean YET ... not someone who said they had Lyme Disease after they showed negative for CCSVI) ... then we can talk.
Until then ... I think this describes the situation of the persons that post on this thread (and any other thread knocking Zamboni's RESULTS ... now trying to play it as how do we diagnose it as more doctors are starting to see CCSVI does play a role in MS).
