Currently, hepatic venous pressure gradient (HVPG) was the reference standard for evaluating portal pressure in patients with cirrhosis. However, the practice of HVPG is limited to require the extensive experience and highly specialized centers. In recent years, non-invasive methods were proposed to predict the degree of cirrhotic portal hypertension. Of them, liver stiffness measured by FibroScan had shown good performance for predicting clinically significant portal hypertension. However, the correlation between liver stiffness and HVPG was poor when HVPG was more than 12mmHg. Since the spleen was stiffer than the liver, the current vibration-controlled transient elastography examination is dedicated to the liver, rather than the spleen. Very recently, a novel spleen-dedicated stiffness measured by FibroScan was proposed. The prospective, multicenter study aims to evaluate the correlation between SS (measured by the novel FibroScan) and HVPG, and further develop a novel model based on SS for predicting the liver decompensation in patients with compenstaed cirrhosis.', 'detailedDescription': 'Portal hypertension contributed to the main complications of liver cirrhosis.
