Something that I have read about is "filters" in the Superior Vena Cava that are meant to catch embolisms, thromboses, etc., before they reach the lungs or heart. My understanding is that they are a temporary measure, until the intervention site has become static. That might take care of some of the migration issues, but then there are the long-term viability questions. I'm hopeful of living another 30 or 40 or 50 years, and wonder how long the stents can stay there.
For me, it will come down to an informed position after the imaging, as Zeureka wrote, with the final choice made when they are actually in the veins. My feeling right now is, no stents, unless the vein snaps back immediately with the ballooning. I'll take a year (or however long) of relief, and wait for the science to catch up. If I restenose and have to go back, I will. Hopefully, by that point I will be able to be treated at home.
My biggest problem right now is an inability to think clearly about anything, and a lack of information on stent science.
edit - good on you, Nunzio, for the short answer. Brevity is a challenge for me. Grin
