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.
Both TIPS and portacaval shunting effectively reduce portal pressure but share the risk of hepatic encephalopathy (HE) due to bypassing the liver's detoxification process. In TIPS, HE symptoms can often be managed by adjusting the stent, whereas portacaval shunting provides a permanent solution without the ability to make such adjustments.
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]

The Pringle manoeuvre is used during liver surgery and in some cases of severe liver trauma to minimize blood loss. [1] For short durations of use, it is very effective at reducing intraoperative blood loss. [2] The Pringle manoeuvre is applied during closure of a vena cava injury when an atriocaval shunt is placed. [citation needed]
