I re-post a question regarding an alternative phlebography imaging technique (possibly a kind of shortcut/speed-up?):

What is your take on this imaging technique of the azygous I've heard of recently - the so called "occlusion phlebography", with the following setup:
Catheter is fed into the upper part of the azygous and then the vein is closed near its confluence with SVC by means of a compliant baloon inflation, so that blood flow towards heart is temporarily disabled. Then with only a single dye injection, the whole azygous system becomes visible at once (assuming the dye can flow backwards into all veins - would this apply only for a healthy azygous system?). The idea here is to possibly replace multiple step-wise dye injections typically done while moving the catheter tip upwards from the very bottom. Would you find such type of images interesting, at least to get a first global picture of the azygous system? Do you see any issues with such an approach?(Unfortunatelly, I do not have any images to show here)
All the best for 2011!
