I am new to MS but I have been an RN for close to 40 yrs.
I have been to be a somewhat focused "nerd" type of nurse. Now CCSVI seems to be ( as reported by Zamboni) a host of different blockages, stenosis, atresia, anular rings, webs, etc....by location and degree they seem to have degrees in the interference of normal flow and location. He documented in the initial study dated Dec 5 2008 that he had lumped them into 4 types A,B,C, D....... the anomalies causing reflux but the amount of involved vessels (locations) and extent of blockage being different & in amount of reflux being different . The locations of MS lesions ( on MRI) created by the flow of the reflux could also be seen to be in patterns.
Now we get to the why......if congenital, don't we get MS until later and varying ages........this might have to do with the amount of the debris deposited ( iron, etc) Think of a partially clogged sink- think of dish water- water in ,used and dirty and slow out- leaves dirty residue.........the slower the drain the more time for crap to be on the sink walls. Then you add the sheer stress of reverse flow and interupted endothelium which has the debris ground into it. I think the lesions may have formed as the bodies way to try to protect itself from the encroachment. The macrophages ( the garbage men of WBCs) are often found in MS people to be laden with iron. Maybe they are attempting to remove it?
Now remember the human body wants to be efficient.....and its immune system compensates well and for a long time in a young & otherwise healthy person, but when pushed it has a tipping point. Some people have great immunity and some do not.....this is inherited but can be suppressed or boosted dependent on environment- ie smoking, diet, exercise,etc
I think the immune system tries hard to keep up and remove the debris (remember this is over years) thus over a long time the immune picture. We see in the snapshot of a hematological examination done after the fact- we are talking about and over active- stressed immune system potentially from quite early on in life its been on overdrive.This seems more plausible to me.
As for the twins ,their DNA is the same ( thus their anomalous stenotic anatomy) but the debris would be different in them depending on exposure- esp to heavy metals, diet, and everything that has entered the individual and influences ones immune system. This may explain why only one twin develops MS. Congenital anomalies of all sorts are seen in families yet to differing degrees.
I am very hopeful that CCSVI and angioplasty will impactand potentially change MS as we know it now. Some day it might be just a minor inconvenience with an easy low risk "cure", that needs occasional monitoriing and an immune system that needs a boost after being chronically over worked.
I can not wait to find out.
The things that will be found out post CCSVI discovery have just begun.
These are exciting times.
Bravo to all the pioneers!

Doing extremely well-
