Portography

Portography is a medical imaging technique used to visualize the portal vein and its branches in the liver. It is often used in the diagnosis and treatment of various liver diseases, including liver cancer and cirrhosis.

Procedure

Portography is typically performed using one of two methods: percutaneous transhepatic portography (PTP) or splenoportography. In PTP, a needle is inserted through the skin and into the liver, where a contrast agent is then injected to highlight the portal vein. In splenoportography, the contrast agent is injected into the spleen.

Uses

Portography is used to diagnose and monitor a variety of liver diseases. It can help identify blockages in the portal vein, which can be a sign of liver cancer or cirrhosis. It can also be used to guide treatments such as transjugular intrahepatic portosystemic shunt (TIPS) placement.

Risks

As with any medical procedure, portography carries some risks. These can include infection, bleeding, and adverse reactions to the contrast agent. However, these risks are generally low and the procedure is considered safe for most patients.
