Debbie ~ Medical jargon is beyond me. But, do you think it might be the same as an intrahepatic portosystemic shunt?

IMOM had a case on this: http://www.imom.invisionzone.com/com...showtopic=2619 "Mya is a 4 month old Shepard/Mix that has been diagnosed with an intrahepatic portosystemic shunt. The procedure for this is called Percutaneous Transjugular Coil Embolization. Treatment for Mya is only available at MSU and U of Penn.

She found a wonderful vet - Dr. Beal at MSU (I think that's Michigan State) - who did a lot of research and was able to help out this poor pupper. Last I heard, Mya was still going strong.

If it's the same thing, you might contact IMOM. I'm sure they would be happy to share what they learned during this case. Also, her foster mom could give you more info. http://search.petfinder.com/petnote/...d=8059341%2522
