This Is MS Multiple Sclerosis Knowledge & Support Community

Are there any research findings about the site of vein narrowing, that is, which vein and where in the vein, and particular MS symptoms?

on page 1352 Dr. Zamboni notes this about PPMS patients in his study:

"Type D pattern (18%) is characterized by the multilevel
involvement of the AZY and lumbar systems. Association
with the IJVs was observed in approximately 50%
and caused an additional obstruction in these patients.
It was observed in two of 35 RR patients, in one of 20
SP patients, and in nine of 10 PP patients."

So there is a correlation between type of MS and location of stenosis.

Thanks for that valuable information....The more we know as patients, the more in-depth the discussions with the MD can be. I have SP and when it's "MY TURN" I'll be armed with even more information, now...Thanks, again

I was looking for the very same thing...


I recently had doppler and they found #2 or B (Zamboni criteria) which goes along EXACTLY with my symptoms.. very amazing.
