A portosystemic shunt or portasystemic shunt (medical subject heading term; PSS), also known as a liver shunt, is a bypass of the liver by the body's circulatory system. It can be either a congenital (present at birth) or acquired condition and occurs in humans as well as in other species of animals.
Transjugular intrahepatic portosystemic shunts are typically placed by an interventional radiologist under fluoroscopic guidance. [9] Access to the liver is gained, as the name 'transjugular' suggests, via the internal jugular vein in the neck .
A portacaval shunt (portal caval shunt) is a treatment for high blood pressure in the liver. A transjugular intrahepatic portosystemic shunt (TIPS) is an artificial channel within the liver that establishes communication between the inflow portal vein and the outflow hepatic vein. It is used to treat portal hypertension.
While awaiting transplantation, people with HRS often receive other treatments that improve the abnormalities in blood vessel tone, including supportive care with medications, or the insertion of a transjugular intrahepatic portosystemic shunt (TIPS), which is a small shunt placed to reduce blood pressure in the portal vein.
Typically, treatment consists of addressing the underlying portal hypertension. Some treatments include portosystemic shunting, ligation, and under-running suturing. [5] Insertion of a transjugular intrahepatic portosystemic shunt (TIPS) has been shown to alleviate varices caused by portal hypertension. [1]
Shunts must be placed early after diagnosis for best results. [20] TIPS (transjugular intrahepatic portosystemic shunt) has replaced shunt surgery as it is less invasive and overcomes intrahepatic outflow obstruction by diverting hepatic and portal blood flow to the inferior vena cava. TIPS accomplishes the same goal as a surgical shunt but has ...
Treatment often involves a low-salt diet, medication such as diuretics, and draining the fluid. [3] A transjugular intrahepatic portosystemic shunt (TIPS) may be placed but is associated with complications. [3] Attempts to treat the underlying cause, such as by a liver transplant, may be considered. [4]
Treatment of gastric varices can include injection of the varices with cyanoacrylate glue, or a radiological procedure to decrease the pressure in the portal vein, termed transjugular intrahepatic portosystemic shunt or TIPS. Treatment with intravenous octreotide is also useful to
