Ok, so I was totally wrong - but not in a bad way. All three areas that were ballooned are still open except for a slight stenosis in my upper left IJV (not enough to go in and fix unless there's something else).
Here's what he found on my MRV - my right sigmoid sinus (see this link; it's labeled "PARS SIGMOID": http://en.wikipedia.org/wiki/File:Gray488_blue.gif
) is ALMOST COMPLETELY OCCLUDED - to the point where all of the blood is draining on the left side. He said it's something he can fix and while he's in there he'll also look at my upper left IJV and balloon again if needed.
He didn't see it on the venogram because he was only looking at my jugulars - the highest he went was right below it.
He also said that it will definitely need to be stented and that at some point in the future (years), so will the upper left jug.
He's going to the professional symposium on the 26th and will talk to one of the doctor's about my case. I'm going to follow up with him that week when he gets back and he said we can do it in August or September.
This is so freaking exciting! I was totally off base - but that's ok. It can be fixed!
