This Is MS Multiple Sclerosis Community: Knowledge & Support

This statement contradicts itself. If a positive result for stenosis disappears the next day, then it can't always be positive.

By the way, how do you know the methods were improper or not efficient?

this is actually a very good point. Dr. Zamboni and Dr. Salvi worked in cooperation--each contributing in their area of expertise when studying and writing up their research. Hearing them speak together in Bologna was very illuminating. It is too bad Dr. Salvi was not able to speak at the AAN conference (I guess because his English is not as good as Dr. Zamboni's)

were any vascular doctors involved in this study? Who tested the patients?

Also--agree with Bob--we need a means to measure vascular changes in real time when going from supine to seated. (Why the transcranial doppler seems essential) I'm wondering how the vertebral veins- the venous drainage when upright- fit into this theory, since Mitch (enjoyingtheride) showed stenosis in his vertebrals when tested in Brooklyn. But that's another thread another day...

CCSVI in MS

In the world of statistics, their study is insignificant. After 30 years of intense engineering, it is my opinion that the should not have even published their paper.

Waste of time, and they are grasping at straws.

You tend to get stuck with petty semantics and overcomplicate things when they are not necessary.
When you find a -ve, you need to sample many more times.
When you find a +ve, you can probably leave it there.

Medicine is full of such methods. When a test for a bacterial infection comes out -ve and Dr still strongly suspects same issue, he repeats after sometime.

I've listed the names and professions in the second entry of this thread. No vacular experts here. I assume they did the tests themselves, as it isn't stated otherwise in the study. But they used Dr. Zamboni's protocol and looked for the five patterns Dr. Zamboni has defined for CCSVI in upright and supine position.

This is not petty semantics. Many of these testing methods (MRI, MRV, ultrasound, etc.) are open to some interpretation, coupled with the facts that not so much is known about the venous system, there's some disagreement among vascular experts on exactly what is abnormal, and CCSVI is a pretty new concept. So a "positive" result may not really indicate any problem, and besides leading to unnecessary intervention, just muddies the water about what causes MS. This why I think this issue is just more than petty semantics.



I don't know what your calling ve. But are you saying that if you get a positive test result, then it's correct, but if you get a negative one, further testing might be necessary? If so, you can't be serious.
