摘　　要：Portal hypertension(PH)is a commonly observed syndrome in patients with cirrhosis and other chronic liver diseases(1).It is closely associated with severe clinical complications,including upper gastrointestinal hemorrhage,ascites,hepatic encephalopathy,and liver failure(2-6).Portal vein pressure(PVP)is a prognostic indicator for patients with cirrhosis,and PH is a contraindication for hepatectomy(7,8).Currently,the gold standard for assessing PVP is the measurement of PVP gradient[hepatic venous pressure gradient(HVPG)],which is indirectly determined by placing a catheter in the hepatic vein(3).
