Thank you Natalie. It's all so very interesting.

Sal and others who may be concerned, arteries and veins are built very differently, and you were quite right when you mentioned that veins are thinner and more fragile than arteries, but except for the Pulmonary veins, all veins lead away from an organ.... the brain included.

Also, where arteries have thick muscular walls, veins have valves that stop the backflow of blood. These valves are strong enough to keep blood from travelling backwards, so they should be strong enough to prevent a stent from moving backwards (against the flow of blood) from the neck up to the brain.

No-one wants surgery, and no-one wants stents, but if I had to have them I would. I'd not be concerned that they might move backwards, up the neck into the brain.

Just the same, let's hope that none of us ever need them.
