Hi fern ,
if I recall correctly the ones that had mainly vascular problems seemed to have better results from surgery- especially if it is a clear cut case of vascular compression. Possibly why there hasn't been a lot of replies to your vascular questions - they are not on the forum much anymore.

But still you would want to find the best and most knowledgeable and experienced surgeon that you can find - not one who doesn't understand all the details of TOS and pain relief meds.

If anyone has had a test like that?? -
don't they usually state the percentage of compression in the results??

my thought is - it could be a 10% or 80% - you should know how much it is before deciding on surgery. Just due to possible scar factors post op.
or request copies of the pictures/scans/tests for you own records and info.
Those are good to have anyway.

I also suggest getting second {or third} opinions and not from this same drs colleagues.
