They made a youtube video too:The study’s key findings are that while the treatment is safe and was not associated with serious adverse events, it did not provide sustained improvement in MS patients.
What to make of discouraging news such as this? We've been waiting on this study since it began in 2010. It's a small study so that might explain the inability to find results (although it also suggests that the beneficial effect that might be captured in a larger trial would be minor rather than major). The techniques used were 2010 techniques so a trial begun today using experienced IRs could see better results. Patient selection could be changed.
I have no doubts from my personal experience that the procedure worked wonders for me. I see the difference every day even two years later. If this can help people, I want it to be available to the people it can help; and I want the researchers to identify who those people are so that no money is wasted, no unnecessary risk is taken, and no one lives for one moment with symptoms that could be alleviated through venoplasty.
