I am new to shunt hunts but wanted to give this one a try. The dog is about 1 year old, and
has very elevated bile acids and low BUN. She is not clinical. I *think* this may be a splenocaval shunt but wanted to see if you were able to confirm (or refute) that based on these images.
Thanks!

Your second video is
Your second video is suggestive just look at the dorsally directed serpentine vessel deriving from the portal vein. The cvc and ao have a 1:1 ratio in your images so it may be a splenoazygos entering in the aotric hiatus. cant be sure but its suggestive. If you can get mor eviews review the shunts tint he archive first by searching “shunt” in the basic search.

and check out the shunt abstract from ECVIM 2010

I looked for the double aorta
I looked for the double aorta and didn’t see it. Maybe I’ll try getting her back in to look again. I was thinking the shunt terminated directly in the CVC . Does it look to you like it may continue cranially along the CVC as a separate vessel then join the azygous? If so, maybe I could follow it to where it does that? Thanks for the advice!

It may go into the CVC just
It may go into the CVC just let up the pressure on the cvc because you naturally compress it there with the maneuver. Once you are on the cvc and ao lined up as above let up and see if the cvc gets big wihtout pressure then that would make sense for a cvc entry of the shunt but doesnt make sense if the cvc and ao are the same width.
