Congenital portosystemic shunt

257:. If the anastomosis occurs outside of the liver, the shunt is considered to be extrahepatic. On the other hand, if the anastomosis is located within the liver, it is considered to be intrahepatic. The clinical manifestations of intra- and extra- hepatic portal systemic shunts can be similar; however the pathophysiology and treatment of the two types are distinct. 277:

Once the congenital, and isolated, nature of the shunt has been ascertained, closure by surgical intervention is usually recommended. Shunt closure prevents the development of complications in pre-symptomatic subjects and

A CPSS results in a direct communication between the portal circulation and the systemic circulation. This breaks down the separation between these two systems which is crucial in ensuring normal physiological function. A reduction in the proportion of blood flowing from the digestive system to the

Spontaneous closure of CPSS can occur in some anatomic forms during the first two year of life. However, in instances where spontaneous closure does not occur, radiologic or surgical closure of the CPSS is recommended to prevent, resolve and/or stabilise complications.

Blood leaving the digestive tract is rich in nutrients, as well as in toxins, which under normal conditions undergo processing and detoxification in the liver. The liver's position downstream to the intestines in the body's circulatory system - the hepatic
