Yes, I am pretty sure this has happened. Wasn't Dake often adding new stents on the follow-up two month visit?
I can't say I fully understand the topic of narrowings, but here is what I think I know: a narrowing in one part of the vein may not need treatment where it's at, it may be indication of a malformation somewhere lower down. It's all blood flow. Narrowings, if they expand under IVUS, may not be stenosis or malformations but might be the result of lower blood inflow...less blood is flowing in because less blood is flowing out, so there is a blockage somewhere, but if the narrowing expands under IVUS, the blockage is not there. (And if it's a new narrowing, I would think it's pretty certain that it would expand under IVUS and that it's not a fixed solid stenosis, because if it was it would've been there the first time.) The idea is that there is a problem lower down, the blood flows a short bit up from there and out the collaterals, and higher up is the narrowing because there is less blood flowing in, because of the lower-down problem.
If it were me and I still had a higher-up narrowing, I'd keep trying to find a doctor willing to look for a valve or membrane or something lower down...and hopefully skilled enough to find it.
Glad to hear you are feeling better again and hope it stays this time!!
