Yes, and this study also shows how refluxed blood does make it eventually back to the heart, through collateral or contra-lateral pathways, but first (in this case) it has to get across to the other side veins through the dural sinus. I imagine this was discovered while trying to treat symptoms, and a non-drug-based approach obviously worked. Of course this was before CCSVI, and before Dr. F met Dr. Z, resulting in the well-known ice-cleaning machine slide being shown at an MS Society presentation...
I think those lab mice need some doctors more than humans do.
