A TIPS procedure decreases the effective vascular resistance of the liver through the creation of an alternative pathway for portal venous circulation. By creating a shunt from the portal vein to the hepatic vein, this intervention allows portal blood an alternative avenue for draining into systemic circulation.
A portacaval shunt, portocaval shunt, or portal-caval shunt is a surgical procedure where a connection (a shunt) is made between the portal vein and the inferior vena cava. Under normal circumstances, the portal vein drains blood from the abdomen to the liver.
Hepatic encephalopathy type B may arise in those who have undergone a TIPS procedure; in most cases this resolves spontaneously or with the medical treatments discussed below, but in a small proportion of about 5%, occlusion of the shunt is required to address the symptoms. [9]
A transjugular intrahepatic portosystemic shunt (TIPS) is a procedure an interventional radiologist performs to create a shunt (essentially, a new conduit allowing for blood flow) between the hepatic inferior vena cava and the portal vein, a vessel that returns blood from the intestines to the liver.

Preoperative PVE is a very well tolerated procedure with extremely low mortality rates (0.1 percent) and technical failure rates (0.4 percent). [3] Complication rates from the procedure are low as well (2–3 percent) and include portal vein thrombosis, liver infarction, necrosis, infection, pneumothorax, and other risks as listed above. [3]
