It is uncertain whether surgical portosystemic shunting favorably modifies survival.

Consequences include accumulation of toxic metabolic wastes, reduced synthesis of key proteins, increased portal venous pressure, and portosystemic shunting.

Anomalies of the portal venous system leading to portosystemic shunting, although they are infrequent, should be considered in the differential diagnosis of hyperammonemia.

No cirrhotic patients (20 of them being Child-Pugh class A, 2 class B, and 3 class C) had undergone portosystemic shunting or liver transplantation.
