Dr. S does having Ultrasound testing give any sort of flow indications in cases like the one above?
It seems it could be to do with the flow improvement by making the valves slightly more open and in still in one piece as opposed to being fully against the wall and then returning/healing to original configuration and symptoms returned prior to seeing you?
Yet the end result was a situation of the valves partial function or total dyfunction destroyed and the residual remains attempting to reattach/heal and recreating a stenosis?
Nigel, thank you for this discussion. It leads me to discuss what i think it sreally going on with the valves.
Integrating what i see by coppler ultrasound, venography and IVUS, I am of the opinion that there are many variable possibilities. I say possibilities because our imaging is still imperfect, even with IVUS. Perhaps the next iteration of IVUS, the so called high resolution IVUS, will expand our understanding. For the most part i now think that the abnormalities at the valves include stenoses valves of thickened tissue that does not open, thick valves that are scarred together, thick valves with septums attaching to the vein wall preventing opening and closing, valves associated with webs that are tissue bands and cells that restrict flow. true full septums that divide the lumen of the vein into segments and each segment has less flow that their total area. I am sure there are other variations. I agree that pathology studies will provide new insights, but these are are not perfect either because what they show is not identical to what is seen in a living beating flowing vein.

Is there reflux more pronounced and regular now?
Again, Negel, there are two kninds of reflux, reflux of blood flowing up from the heart and refluxifrom blood flowing down from the brain. Very different ideas.

The flow speed and volume in each treatment before and after might be of interest?
probably, blut this is not all about flow

It would be interesting to be able to identify what the improvement is from the first treatment, it almost sounds like the recovery in some Stroke Treatments?
only in a general sense. Stroke is so very different from this
Is there a problem remaining with CSF flow that hasn't returned to normal or first treatment quality. The CSF flow and symptoms are very similar to CCSVI and MS symptoms?
Quote:
Problems such as Chiari Malformation issues which are often related to the slowing of CSF because of restricted flow in the region of the Brain Stem (have or share symptoms with MS and CCSVI)?
yes, in some way, i think that venous outflow obstruction impedes CSF drainage. Dont the ventricles drain through the pacchionian granulations into the veins?
Quote:
Changing the vascular flow also changes the CSF and the Arterial flow and all three are interlinked and dependent on each other, change one and you change them all?
i agree
Quote:
Adjustments to the Atlas/C1 are giving in some cases the same benefit as PTA and the flows improvements have been measured, (before and after the adjustment). Results are published by the way. This change in symptoms was attributed to CSF flow changes measured by MR, they occurred as quickly as on table improvements with some PTA? Co-incidence or part of the puzzle?
interesting, can you send me the references
Quote:
Having enough information detail with the PTA treatments so that observations can be made and understood with any change in symptoms, BUT which detail, there's a missing piece, what is it, HELP?
