Here is My Question:
What do you think about this?
I think we can wait until this is peer reviewed by autonomic specialists AND multiple controlled trials are done with confirmatory results; There is a significant literature on transvascular (venous and arterial approaches) stimulation or modulation, usually through pacing or ablation, of the autonomic nervous system for arrhythmias and even refractory hypertension; but one would not expect any prolonged effects with balloon dilation of a vein. One could argue that this procedure represents nothing more than the "liberation procedure" searching for a mechanism of action.
This happens all the time in medicine, and there is nothing wrong with this approach; remember interferons were first used in MS for their proposed anti-viral effects. But no one would have pursued these studies further without preliminary controlled studies showing a benefit. Uncontrolled studies with subjective outcomes rarely provide any significant evidence of benefit.
This procedure is similar to the liberation procedure advocated for CCSVI and we know the outcome of that story.
