Keep in mind, in addition to concerns about thrombosis and stenosis in of the veins above and below the stents, the question of long-term patency is a complete unknown.
In the few patient groups that have received venous stents in the past (some cancer patients and end-stage renal disease patients) the patency of the stents was less than 50% after one year. That means half of the stents failed within one year of implantation.
Here's some data on renal disease patients:

Now, you can't necessarily compare the experiences of one patient population to another, but such statistics do warrant cause for concern. The stents currently being used were generally designed for use in thoracic arteries, where they are not subjected to the twisting, bending, and torque that they undergo when placed in the extremely flexible human neck.
Questions about stem patency won't be answered for several years, as time goes on and assessment can be made of those patients who have stents in their jugulars.
Given all that we now know, I would personally not submit to a stenting procedure. Of course, each patient must make their own assessment…
