In this procedure, the provider incises a patient’s thoracic and abdominal area and creates a portocaval venous anastomosis, or a connection between the portal vein of the liver and the inferior vena cava. The provider performs this procedure as a treatment for portal hypertension, which often occurs due to a narrowing or blockage of the portal vein. This procedure lowers the pressure in the veins of the stomach and esophagus, or food pipe, and prevents serious bleeding in the gastrointestinal tract.
