could lesions in the spine/brain cause a reduction of blood flow leading to pressure and stenosis of other veins
Yes it can cause problems--- but it would be on the OTHER side of the brain circulation.
It is known in the medical world that people with cirrhosis of the liver get scarred areas that make it so the blood can't get through the vessels in that hardened scarred area well.
The vessels in the area where the scars are can't stretch or flex, they are rigid, tight, small and inflexible. as a result the nomral volume blood can't get through there, and it backs up causing stretched vessels on the downstream side of the liver in the esophogus, which are called esophogeal verices.
These can kill alcoholics, and they are caused by those hardened scars in the liver, there was actually nothing wrong with the esophogus except that it was down stream from the liver...in other words in terms of circulation the blood flows from the heart through circulation to the esophogus first then into the liver, but because the liver is all hard and the blood can't get through, the thing that gets hurt is the perfectly healthy esophogus vessels because the blood os backin up all the way to there.
So it could be possible that MS lesions might cause a problem BEHIND them in the circulation. The hardened areas might be able to cause a backup in the same way.
But that would be on the arterial side for anatomy to allow that to happen. That is not where these stenoses are.
These stenoses as Jeff and I had, as well as the stenoses Zaomboni documents are on the OTHER side of the brain, upstream from the brain.
It is almost like you are looking at a pond that has a stand of aspen on its edge that is flooded where the trees are dying and wondering if the dying trees caused the beaver dam that is blocking the creek.....
The fact that these stenoses are downstream of the lesion means that they are not actually vulnerable to anything going on in the lesion area, it has to be the other way around...in the same way that the beaver dam on the creek can't cause a problem 1/4 mile downstream--even though it is causing havoc behind it, upstream.
The only way there could be some kind of connection is if you argued that there is a system wide inflammatory response which causes both brain lesions and these stenoses. however, people treated with suppressives have just as many and just as bad stenoses as untreated people so that possibility is really unlikely.
I'm not offering medical advice, I am just a patient too! Talk to your doctor about what is best for you...
