CeImages 1a, 1b (R-IJV, lateral): Is the vein to the right of the Sigmoid sinus the Right VV?
I think so.
Image 3a (R-IJV, front): I think the blue arrow is the transverse dural sinus.
That sounds right
Images 2 and 3b (L-IJV, front): Any guess as to what the "squiggles" are? Vertebrals? Collaterals? Plexus veins?
I don't know. They are the same squiggle veins that are on my original image before my procedure in February:
Image 4 (L-IJV, lateral): Again (see Image 1a, 1b), is the vein to the right of the Sigmoid sinus the Left VV?
I think so. What else could it be? My VVs are on the large size too.
Do you have any post-valvuloplasty images showing if the VVs stopped "lighting up" with dye, or would that necessitate DrS having to go back into the SS to release more dye and use more radiation?
I believe it would have required him to go back up into the sinus or near it.
Is it safe to believe that the VVs won't fill with dye anymore once the lower IJV valvuloplasty is completed?
I don't know. My verts are well-developed, for which I am grateful, they've served me well. I wonder if they would still take more than average just because they're there and they can? Or would the flow of the jugular win out? I think I have large verts on the other side too so I'll stick with my answer that the left side would, post-venoplasty, look more like the right side.
I'm still unsure of where the renal veins are?
I am not sure where they are in this image.
Here is a link to a great PowerPoint presentation that shows the dural sinuses and the bottom of the skull in all their glory (the d/l might be a bit slow). One can really see how vulnerable all the vessels and nerves are to shifts in the skull: www.similima.com/ppt/anatomy/anat-cranial-fossa.ppt
Thanks for the link! I will have to watch it tomorrow, I got defeated partway through the first of Dr. Tucker's youtube videos....did you know that two waves going in the opposite direction, when they meet, it'll combine the pressure of both waves?
