Effect of hepatic venous pressure gradient in different hepatic venous branches on assessing portal hypertension in cirrhotic patients

Figure 1 Hepatic venous pressure gradient measurement. A: Right free hepatic venous pressure (FHVP); B: Middle-FHVP; C: Left-FHVP; D: Right wedged hepatic venous pressure (WHVP); E: Middle-WHVP; F: Left-WHVP.

Figure 2 Flow diagram of study population. HVPG: Hepatic venous pressure gradient; PPG: Portal pressure gradient; HBV: Hepatitis B virus; ALD: Alcohol-related liver disease.

Figure 3 Bland-Altman plots and box plots of right hepatic venous pressure gradient, middle hepatic venous pressure gradient and left hepatic venous pressure gradient. A: Hepatic venous pressure gradient (HVPG) in all patients; B: HVPG in hepatitis B virus; C: HVPG in alcohol-related liver disease; D: HVPG in hepatitis B virus + alcohol-related liver disease. L-HVPG: Left hepatic venous pressure gradient; M-HVPG: Middle hepatic venous pressure gradient; R-HVPG: Right hepatic venous pressure gradient; HBV: Hepatitis B virus; ALD: Alcohol-related liver disease; NS: Not significant.

Figure 4 Middle-hepatic venous pressure gradient and portal pressure gradient measurement in the pilot cohort. A: Correlation between middle-hepatic venous pressure gradient and portal pressure gradient; B: Agreement between middle-hepatic venous pressure gradient and portal pressure gradient according to Bland-Altman plots. M-HVPG: Middle hepatic venous pressure gradient; PPG: Portal pressure gradient.
