Here is what I think we can take (simply) from the article:
- Collateral veins can substitute for outflow in lieu of typical outflow to the great vein of Galen (supports the collateral veins seen in CCSVI);
- Simultaneous obstruction of both the great vein of Galen and the basal veins will result in serious injury (and even death); however, some obstruction can be survived...with damage in a variety of pathological forms (supports MS as a potential byproduct of blood flow obstruction).
Three veins angioplastied. One renewed life.
