Forgive me I feel compelled to add to this thread so it is here that my dopplers at my local University were of limited value they showed some reflux and turbulence on the vertebral vein esp on the left but that was all--they felt it was very mild and not really significant...even though interesting and fun given the research and the fact I had MS.....they certainly did not see anything that they considered repairable at all.
then I went to Stanford and had MRV where we saw the nearly total blockage of both jugulars really significant blockages and obviously in need of repair.
Then Stanford wanted a complete data set so the did dopplers again, and that lady refused to believe there could be anything of value by doing them she claimed blood refluxes up to the brain all the time, that this model is stupid etc . She saw nothing and claimed it was totally normal---I told her I'd had dopplers at my Univeristy and had VV reflux and she said no that is normal nothing there at all, and when I said I'd already had MRV that morning at Stanford and the jugular blockages were there she said no I could not or she'd have seen turbulence and she did not see any, it was a utterly normal exam.
Dr Simka says it is possible to detect the presence of high jugular blockages if you know what to look for, one thing is a higher than expected flow in the vertebrals which my local university had stumbled onto. But you have to know what to look for and want to find it. Obviously if your agenda is to prove this is all nonsense you will find nothing even in the face of gross blockages in excess of 90% on the jugs.
What was worse to me was the arrogance and assurance in the face of obvious data that showed her evaluation was incorrect. MRV's should be better than dopplers most of the time, but Holly's MRV did not show azygos issues and they found that with the venogram on the operating table, so MRV is good but not perfect either even in a trained office that has done it several times now...
I mention it on this thread only so people reading it will be clear that you may not be able to actually get a truly certain answer if you get studies done by people who are not familiar with this material.
It is not like an x-ray, it is very operator dependent meaning that the operator makes the difference as to what is seen and how it is able to be read or interpreted. I know one thing Dr Zamboni wants to do as soon as he can is train people what it is they need to look for.
Ok sorry about that I just wanted it in this thread.....
I'm not offering medical advice, I am just a patient too! Talk to your doctor about what is best for you...
