Porto-Systemic Anastomosis

Porto-Systemic Anastomosis (PSA) is a vascular connection between the portal vein and the systemic vein in the body. It is a type of bypass surgery, which is used to treat portal hypertension, a condition in which the portal vein, which carries blood from the digestive organs to the liver, becomes blocked. This bypass aids in restoring the flow of blood and relieving the pressure on the portal vein, thus lowering the risk of further complications, such as varices, which are swollen veins in the esophagus or stomach. PSA is also used to treat a variety of other diseases, such as Budd-Chiari Syndrome, Budd-Chiari-like Syndrome, or portal vein thrombosis. This technique has proved to be a life-saving surgical option and can improve patient outcomes and overall quality of life.
