Okay, a vet called me back, and my fax picked it up and disconnected us! This can't be good.... calling him back....
It's operable! It's a Splenocaval extrahepatic shunt (there are 3 types). Here's a link to what it looks like (includes US videos):
Complications after surgical attenuation of congenital extrahepatic portosystemic shunts in dogs can be prevented by intraoperative Doppler ultrasonographic assessment of portal hemodynamics - (c) Veterinary Sciences Tomorrow

What to do now? They recommend "L/D, Lactulose, and metronidazole until surgical intervention can occur in which Ameroid Constrictor therapy placement, liver biopsy and cysotomy should all be performed with apropriate analysis and histopathology to rule out concurrent MVD".
I told him to call the specialist and set up a consult.... and now the bad news: he's guessing it may run over $4000.00.
Waiting some more... and see.

Oh and Thanks to all who responded for the well wishes.... please keep Tinky in your prayers....
