The procedure is typically performed by radiologists. Many patients receive a local anesthesia to numb a small area of the skin plus sedative and pain medications. In certain cases, general anesthesia may be used, where the patient goes to sleep. A needle is initially placed in the jugular vein in the right side of the neck to make a small hole. Needles and long, thin tubes called catheters can then be advanced down to the veins in the liver. A needle is inserted to make a connection between an adjacent vein and a branch of the portal vein. This channel is then expanded, and a tube called a stent is inserted to allow blood to flow more easily through the liver. This tube is left in place.
