Abstract
Spontaneous portosystemic shunt (SPSS) is an important pathological feature in the progression of cirrhotic portal hypertension and acts as the body's compensatory mechanism for reducing portal hypertension. Recent research results show that SPSS is an important link in the development of cirrhosis into the decompensated stage and is also the main cause of hepatic encephalopathy after splenectomy combined with devascularization. Therefore, during splenectomy combined with devascularization, it is necessary to decide on treatment measures such as disconnection, flow limitation, or retention of the distal side as a selective shunt channel according to its location and shunt volume.
