Oh what fun.
The right jugular looks good except for I'd take a closer look in the proximal area with IVUS.
I find it hard to interpret azygous images, so I'd defer to my supervising physician on that (and really on all of this). But I would ask him about the apparent narrowing midway down and the apparent lack of issues up on the arch itself, since that is an area I'd expect to find something.
I would note that the ascending lumbar looks abnormal but would not treat in that area, the veins are too small and the association with CCSVI or MS too uncertain.
The left jugular, is that hypoplastic? Or is the technical term 'a mess.' I'd balloon starting from the bottom, going up, after double-checking drsclafani's thread for what balloon sizes and pressures he's used in hypoplastic veins and repeat ballooning or adjusting sizes and pressures on whatever waisting is found, but with the issues near the skull base I'd leave alone. I would not expect too good of results with that one but perhaps would be surprised.
(please note that I expect to be wrong and most definitely am not a doctor)
