Hepatic venous pressure gradient: Inaccurately estimates portal venous pressure gradient in alcoholic cirrhosis and portal hypertension

Figure 2 Box plots of pressure differences during transjugular intrahepatic portosystemic shunt. A: All patients (n = 134); B: With hepatic vein collateral branches (n = 26); C: With no hepatic vein collateral branch (n = 108). P values were calculated by the paired t-test. WHVP: Wedged hepatic venous pressure; PVP: Portal venous pressure; HVPG: Hepatic venous pressure gradient; PPG: Portal venous pressure gradient; FHVP: Free hepatic venous pressure; IVCP: Inferior vena cava pressure.
