There is another possibility. From the Buffalo results and anecdotal results reported here, it would seem that these stenoses are indeed seen more often in people with MS, i.e. they are associated with having MS. Assuming this, it is possible that the stenoses are a result of having MS, or some inflammatory process associated with the MS.

CCSvI has already been deemed congenital. Italy has also accepted CCSVI as an independent condition from MS.

I guess that if I went to an IR and was told my jugs were fine but he couldnt test the Azygos I would get a Venogram to have them all checked again. Some patients see only Azygos stenosis so I dont see why you would only do half the job. Also, as has been pointed out,there are several other diseases that have similar symptoms to MS.

Until you either get all the veins normally assosiated with MS checked properly or have the other conditions(Lyme etc.) eliminated as a cause of the symptoms you have eliminated nothing. You are back where you started.

There are some DRs out there say that if you were PROPERLY DIAGOSED WITH MS you have CCSVI. That being said, that does not meen you are going to get better after it is fixed.

I think if I was your friend I'd still try to get an MRV and even a venogram. Or just jump straight to venogram. I know there's a good chance the jugs are fine, but still, nothing like a venogram. Especially with the IVUS like Dr. S was using to find problems with valves and flaps and such.

I agree with all you said provided we decide to leave our common sense at home that bad blood in reversing flow is fine; that the reflux we observe in the US is an abberation and should be ignored ...

As some one said - its easy to make simple things complicated .....

He/she never smokes but got lung cancer (about 20% of cases). Why??

But for about 80% of lung cancers smoking is the main cause.

R.

Radon Gas, and enviromental factors like pollution can account for most of that I think.

im still in the camp that believes there is a mechanical purpose to CCSVI - vertebral pinching, etc. This would be found in the 10% or so that are not dx as traditional ccsvi theory

(sorry am not sure I express myself clearly here )

Algis, not sure if this helps but I have seen a paper that indicates that BBB compromised filtering is body's intentional mechanism to let immune cells enter the brain. Indirectly it implies that the BBB filtering is not a static behavior but can respond to body's need by lowering its filtering capacity.

It doesn't seem like you would have any problem with this.

I never suggested either one of these things.

As some one said - its easy to make simple things complicated .....

And it's easy to try to over-simplify things that really are complicated.

And there lies the difference between CRABS who take complicated route and achieve nothing ... imagine if every scientist went about this route ...

If you have an MS dx, you should focus in your brain and spine ;)

Nerves that connect my CNC with my muscle are very long chain of nerves and if that chain is week (mielin naked) than information that they are supposed to deliver can easy fade during trip. Same with backward information.

AD 2: I have MS Dx since last century. I am focused to my brain and spine, but veins... doesn't fit in my hemodynamics equations ;)

My common sence is that 'blood in reversing flow' is hemodynamic imposible, and that so called 'reflux' is just the artifact in bad tuned color doppler machine.

Personal attack. Not cool.

I don't think so. It's just 'Brain storming' ;)

Reflux is a commonly found feature of CVI.

Check out this animation:

The animation is bottom-side-up, since it's of a valve in lower-body CVI; for CCSVI the brain would be on the bottom of the screen with the blood refluxing up towards it.
