Dr Dake told me he expects these to last when I asked him but arterial stents do need replacing often and these in these locations are new use of them so I am not sure anyone should make any promises about that. In other words; how could anyone know?
That is what happens with new treatments, I mean Jeff has had a stent for 7 months or so now I have them for 6. Never before that has anyone put a stent in the jugular veins in those locations for that reason. I can say that mine has worked great for 6 months................

Yeah I would also note that jugs have little pressure compared to arteries, and augment that by saying that they are in a place that gets quite a bit of movement though!

I agree Mark! I am hopeful for those reasons myself that they will be long lived.
It would be tricky to replace them should such a thing be necessary though. It just bears mentioning.

And Dr. Dake told me that he has a patient who has one, for non-CCSVI/MS reasons, for over ten years now...

Boy, I never even considered this. Something to think about for sure. Howver, if mine deteriorate, I'll get them put back if they re-stenose and I'll be saying "'watch my damn spinal accessory nerve!
".

durability of stents

It is difficult to extrapolate the knowledge accumulated so far of the behaviour of arterial stents to the fate of stents in the jugular veins. As it has rightly been said in this topic the mechanism of the obstruction is completely different in the two compartments: accumulation of cholesterol in the inner layer of the arteries, congenital malformation in the jugular veins.
Similarly the mechanism of re-obstruction inside a stent would probably be different.
The possibility, that has been suggested, of resecting the obstructed stent and replacing it with a segment of another conduit is a realistic one (two segments of saphenous vein from the leg can be opened up longitudinally and sutured together to form a cilinder). This would be easy enough in the lower part of the jugular veins, and could be more complicated, I imagine, near the skull.
We are unfortunately in a new unexplored field and we have to wait for medium-term and long-term results to be available. Encouraging is the fact that "so far so good".

Please don't take this as me stating facts, because the mind is a little fuzzy as to aht I was told.... but I believe Dr. Dake mentioned to me that they have been using stents in veins for leg problems (particularly in the hip) for quite a while. This was in response to my question about the issue of stents in veins, etc.

I'm not concerned too much about it, jugs have so little pressure compared to arteries anyways. Only consideration would be the constant flexing and movement in the neck area during the course of a day...

I thought Dr. Zamboni used the balloon style & stretched the vein & then removed. He would do again if it didn't stay open.

I think from what I have read that using balloons is what they did, but also something I read in a different thread suggested that the number of 'restenoses' is greater with the balloon procedure than with the stent. Which is why (again something someone wrote) Dr Dake uses stents...
The other issue here is that of lack of long term data, but in spite of that I think it is worth the risk, what have we got to loose. My daughter is of the group of people who could not live to be totally dependent on others for her daily needs and can only see a short future for herself. If we can change that even for a few years it must be worth the risks.
