Dilated tortuous veins of lower extremities. Other symptoms include fatigue, abdominal pain, jaundice (a yellowing of the skin), nausea, and bleeding in the esophagus of the throat.. In adults, an IVC collapsibility index of greater than 50% is associated with reduced right atrial pressure and severe dehydration, and indicates that the patient needs fluid therapy(23).

Sometimes surgery can widen the veins or switch blood flow from one vein to another. Elevated hepatic venous pressure and a decrease in hepatic venous flow cause hypoxia in hepatic parenchyma, and eventual diffuse hepatocyte death and fibrosis.
