wish I could come up with an experts opinion on this issue, but I haven't one. But in the last view days I read a lot of studies about vein stenting in german and english language. One thing that I noticed: In most cases the stents were placed in patients with severe health problems, many of them quite old (+65, sometimes 80). Many of them had cardiac problems, cancer and/or blood that's likely for thrombosis. Usually when stents are placed, the vein tissue is already damaged and the blood is thrombotic. Though we cannot know the long therm risks of stenting an obstructed but otherwise healthy vein, I think it cannot be compared to stenting an ill, damaged vein with addidional thrombotic blood.
It's kinda hard for me to make clear what my point is in english as it is even hard to do in my native language, I'll try with an example: If you have a drain that drains muddy water and is obstructed by mud that attaches to the drain walls, it is obvious that if you just remove this mud but don't clear the water otherwise, it is likely that mud will attach to the walls again. But if you have a drain that drains clear water and is obstructed mechanically, let's say through a sharp bend, you remove the bend and everything will be fine FOREVER.
Moreover, there are many reports that say that the material of the stents were strongly improved in the last few years, so that you can't compare experiences from even five years ago with today.
Having said that, I think it's an quite encouraging thought but I nevertheless don't want to downplay the risks.
Here's another, quite encouraging story for you (and of course all others, too).
My father was hemophiliac. So he had to inject himself coagulation factors. But the drug was polluted, which led to a cirrhosis of the liver. The docs here in our town said to my father "We cannot do anything for you as it is impossible to transplant an organ to a hemophiliac. You just would bleed to death straightly. Make a good last year to your life." but my mother didn't settle with that and fought until she found some docs that would do the transplantation. Finally she found them and a matching organ was found - four weeks before my father would have fallen into coma. So he was transplanted, he just got an extra dose of the coagulation factors and everything went fine. THIS WAS 17 YEARS AGO. My father has some health problems, but not with the liver, this is just fine. No doc would have forseen this, no statistics would have told that. If he just accepted what studies and even experience and intuition of his (former) docs had told him, he would have died 16 years ago.
