Surgical and medical treatment outcomes for dogs with congenital portosystemic shunt

Congenital portosystemic shunts (CPSS) in dogs result from persistent embryonic or aberrant vasculature that permits blood from the gastrointestinal tract to bypass the liver and enter the systemic circulation. The shunt(s) may lie within or outside of the liver parenchyma and are referred to as intrahepatic or extrahepatic, respectively. Large-breed dogs tend to have intrahepatic CPSS. Extrahepatic CPSS are more prevalent in small-breed dogs. Purebred dogs are more likely to have CPSS than are mixed-breed dogs.
