Portography
Portography
Portography (pronunciation: por-TAW-gruh-fee) is a medical procedure used to visualize the portal vein and its branches. The term is derived from the Latin porta, meaning "gate", and the Greek graphia, meaning "writing" or "representation".
Procedure
In a portography, a contrast medium is injected into the splenic vein or superior mesenteric vein, which are branches of the portal vein. This allows for the visualization of the portal vein and its branches using imaging techniques such as computed tomography (CT) or magnetic resonance imaging (MRI).
Indications
Portography is primarily used to diagnose conditions affecting the portal vein, such as portal hypertension, portal vein thrombosis, and liver cirrhosis. It can also be used to guide certain surgical procedures involving the portal vein.
Risks and Complications
As with any medical procedure, portography carries some risks. These may include allergic reactions to the contrast medium, infection, bleeding, and damage to the vein. Complications are rare but can be serious.
