Splenorenal vein shunt

The clinical application of portal vein shunt for the treatment of portal hypertension has a history of nearly half a century. It has a certain effect on reducing portal pressure and preventing esophageal and gastric fundus varices rupture and bleeding. However, due to the complexity of the operation, the operation has a greater impact on the hemodynamics of the portal vein, and the complications and mortality are higher. Therefore, the surgical indication must be strictly grasped. Shunt surgery can be divided into two types: total shunt and selective shunt. Full shunt refers to the main or main branch of the portal vein to the vena cava system, including splenorenal shunt, portal shunt, bowel shunt, and splenic shunt Surgery. Such operations often deprive the bloodstream of the liver and cause serious complications such as hepatic encephalopathy and liver atrophy. Selective shunting refers to the selective shunting of the spleen and stomach region of the portal vein system to the vena cava system, which saves blood flow into the liver to achieve the purpose of preventing bleeding and reducing liver damage. There are two types of surgery commonly used in clinic: distal splenorenal shunt and coronary shunt.
