my left jugular, procedure #2, five months later:
The end result looks equally good both times.
It has lasted without restenosing longer this time. I am still doing really well.
Even before procedure #2, in the first image of the second set, it is a more functional vein than it was before the first procedure.
In that first image of the second set, it could be restenosis due to scarring, but Dr. Sclafani thought it was restenosis due to residual valve material. Or restenosis due to collagen III abnormalities that made the valve less compliant? It's not clotting and it's not intimal hyperplasia. It could be considered natural narrowing before the jugular joins the subclavian but it was seen that the contrast just sat in the vein, in stasis, not going anywhere. And I had improvements upon treatment.
