A comment on the "duplex" test Lisa mentioned, the first thing that came to my mind (not to disagree with Mark though) is that he might want to try to open both upper and lower narrowings with a balloon first before putting in stents at either height. A possible reason he had speculated to me for why the upper stent fell out (apart from the obvious one that the stent had been narrower to reduce risk of accessory nerve damage) was that putting in the lower jugular stent (after the upper stent) may have changed the flow dynamics of the vein such that the upper segment became wider. Indeed when they did a new venography two and a half days later they found that the upper vein was completely fine, with pressure gradient reduced from 2.5 mmHg to 1 mmHg (he said in a different context that gradients of order 1mm Hg gradients are nothing to worry about, may be just inaccuracies in the measurement). So that would support doing a test starting from both upper and lower end.
We'll take any and all information we can get, especially from other vascular doctors. I'm inferring from this, that angioplasty on the lower stenosis, if indicated, can open up the stenosis up higher?
I'm easy to disagree with, I'm not a doctor!
Good to hear from you Radeck and VERY good to hear there is a possible explanation for the pounding. Is it possible the body can adapt and adjust to the increased pressure radiating outward? Nature is kind of funny like that. I had a neighbor with an OBNOXIOUS lime tree growing over the fence, dumping fruit and leaves. I put a shed in that location, which interfered with the ability of the tree to hang over. It's been two years now, and the tree actually grew UP instead of OVER the roof of the shed.
Bad example for veins duh, but interesting how nature adapts adjusts in ways we can't see in the short term.
