Added to my question earlier today.

We have now learnt that after a CT Scan my wife's veins have problems-1 Her "inferior Vina Cava has a narrow caliber. otherwise narrowing.

2-Her Hi ac vein is also narrowed.

My questions now are, what treatments (Bloodless) are available to help remedy this?.

Please excuse my spelling, but I would hope the experts will know what I am talking about.
