a reason for the discrepancies in % of MSers with CCSVI?

A forum to discuss Chronic Cerebrospinal Venous Insufficiency and its relationship to Multiple Sclerosis.

I have a paper by a french doctor, Franceschi, in which he describes 4 patterns of venous obstruction as observed by Zamboni. My anatomy is not very good, but it looks as though 2 types of venous obstruction involve one or both jugulars and the proximal azygous, 1 involves both jugulars but results in the azygous being overloaded (these 3 types are mostly RRMS and SPMS) and 1 involves the azygous only (mostly PPMS)
If Buffalo didn't look at the azygous, this would account for the differences in results.
Surely this must be wrong somewhere. I hope someone can enlighten me.

My understanding is that the Buffalo results that have been released so far were obtained using a transcranial doppler. The rest of the results, including the MRVs, are still being peer-reviewed or haven't been released and will be in the April paper.

Does the transcranial doppler give any information at all about the azygous? Or does it just cover the head and jugulars? If the latter is true, then suze is right, the azygous has yet to be factored in for the current results but should be in the April paper. There is also still an unexplained difference in that Zamboni found far more azygous stenoses then Dake or Simka have.

Actually it is the extracranial doppler that checks the hemodynamics of the jugulars and vertebral veins and it can also hint to a problem with the azygos vein.
