How long do you think the collateral veins remain viable? I mean after they have stopped filling because the blockage in the jugular is fixed, will they forever be there ready in case the blockage happens again or will they stay permanently closed at some point?
most will just get smaller but remain
others may clot off if there is no blood going through them
i would bet that most will just get smaller but be ready and able should they be needed again
