Portacaval shunting
Definition
 |
Portacaval shunting is a treatment for high blood pressure within a vein that flows into the liver. Such high blood pressure is called portal hypertension.
Alternative Names
Shunt - portacaval
Description
Portacaval shunting is a major operation. The procedure requires a surgical cut in the belly area (abdomen). The surgeon makes a connection between the portal vein, which supplies most of the liver's blood, and the inferior vena cava, the vein that drains blood from most of the lower part of the body.
The new connection helps divert blood flow around the liver. This reduces blood pressure in the area and decreases the risk of liver vein rupture and bleeding.
Risks
Complications from this procedure include:
- Bleeding
- Liver failure
- Worsening of hepatic encephalopathy (a disorder where concentration, mental status, and memory are affected; may lead to coma)
