This procedure is performed to open up the veins of the liver which get blocked due to clotting of the veins. The patient can develop liver failure due to the impaired blood flow out of the liver. The procedure is performed under aseptic conditions in the angiography suite. 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 is also given to ensure that you are comfortable and relaxed during the procedure. Using imaging guidance, a pin hole access is obtained in to a small branch of the hepatic vein in the liver. Then a fine wire is threaded under X-ray guidance through the blocked vein. Once the blockage is crossed, a balloon catheter is used to stretch the blocked vessel, followed by insertion of a stent (cylindrical wire mesh) to keep it open.
