The azygous vein was affected in 55/65 of cases; some of them had a membranaceous obstructions or a twisting, or less frequently, atresias and septums; in 12 cases, the azygous system showed stenosis at several points up to even atresia or agenesis of the lumbar plexuses 12/65 (Figure 2).

The various facilities may not share a similar cross-section of MS disability distribution. I am interested in seeing some of the results broken down across disability level, type of MS, duration of disease, previous treatments, etc., not just according to study or facility. Different variables would be intriguing. I hope I'm being clear -- I'm never sure!
We have found over 95% of patients have azygous vein lesions which have required balloon angioplasty.

expiration imaging was sal's idea. but i have seen this happen on several patients now. so, it may not be the best way to image the azygous.
in this case, I did expiration imaging, followed by ivus which showed no abnormality, and then did the imaging at full inspiration.
