Portacaval shunt

Portacaval shunt is a surgical procedure that creates a connection between the portal vein and the inferior vena cava, which are two major blood vessels in the abdomen. This procedure is typically performed to reduce high blood pressure in the portal vein (a condition known as portal hypertension) that can occur as a result of liver disease.

Indications[edit | edit source]

Portacaval shunt is primarily indicated for patients with severe portal hypertension, often due to cirrhosis of the liver. This condition can lead to life-threatening complications such as esophageal varices and gastrointestinal bleeding. The shunt can help to reduce the pressure in the portal vein and prevent these complications.

Procedure[edit | edit source]

During a portacaval shunt procedure, the surgeon makes an incision in the abdomen and locates the portal vein and the inferior vena cava. A connection is then created between these two vessels, allowing blood to flow from the portal vein directly into the inferior vena cava. This bypasses the liver, reducing the pressure in the portal vein.

Risks and Complications[edit | edit source]

As with any surgical procedure, a portacaval shunt carries some risks. These can include infection, bleeding, and complications related to anesthesia. In addition, there is a risk of hepatic encephalopathy, a condition that can cause confusion and other neurological symptoms due to the buildup of toxins in the blood that are normally removed by the liver.
