摘　　要：Portal hypertension(PH)is a clinical syndrome,characterized by elevated pressure gradient between portal vein and inferior vena cava.These elevated pressures gradient due to increased vascular resistance and/or increased volume of blood flowing through the portal vein circulation,results in blood outflow difficulty from portal vein to hepatic veins and inferior vena cava.
