This procedure is performed to assess the difference in pressure between two different network of blood vessels of the liver (portal vein and hepatic vein). This is performed to evaluate the response to treatment and also to decide if any further intervention is required.

This procedure is performed through a pinhole access in the neck vein During the procedure, local anaesthesia (pain killer) is injected into the skin at the access site to prevent discomfort. An injection of a mild sedative can also be given to ensure that you are comfortable and relaxed during the procedure.

A special catheter (fine tube) with an inflatable balloon at its tip is introduced into the hepatic vein under X-ray guidance. The pressures are measured. This procedure can be performed on its own or along with further interventions to reduce the pressure.
