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

Figure 4 Relationships between the pressures measured in patients with hepatic vein collateral branches (n = 26). A: A scatterplot of wedged hepatic venous pressure (WHVP) against portal venous pressure (PVP); B: A Bland-Altman plot to assess agreement between WHVP and PVP; C: A scatterplot of hepatic venous pressure gradient (HVPG) against portal venous pressure gradient (PPG); D: A Bland-Altman plot to assess agreement between HVPG and PPG. WHVP: Wedged hepatic venous pressure; PVP: Portal venous pressure; HVPG: Hepatic venous pressure gradient; PPG: Portal venous pressure gradient.
