Hepatic Venous Pressure Gradient (HPVG)
HVPG is a clinical measurement of the pressure gradient between the wedged hepatic venous pressure (WHVP) and the free hepatic venous pressures, and thus is an estimate of the pressure gradient between the portal vein and the inferior vena cava. An HPVG of ≥10 mmHg defines clinically significant portal hypertension, and if the measurement exceeds 12 mmHg variceal haemorrhaging may occur.
