Congenital portocaval shunt in puppy

Portosystemic shunts can be congenital in dogs and cats or the result of sustained portal hypertension. They can greatly vary in morphology, with different origin and termination.

Ultrasound is a useful modality to detect direct and indirect signs of portosystemic shunting. The main features of congenital extrahepatic portosystemic shunts are discussed in this video.

For more infomation, consult pages 224-234 of the Atlas of Small Animal Ultrasonography (2nd edition). The reader is also encouraged to review the normal anatomy of the portal system with 3D images in The Liver
