OBJECTIVETo evaluate the agreement and correlation between hepatic vein pressure gradient (HVPG) and portal vein pressure (PVP) in patients with portal hypertension,and explore their clinical value.

METHODSA total of 46 patients with portal hypertension were directly measured the free hepatic pressure, wedged hepatic pressure, portal vein pressure before and after TIPS therapy. The agreement and correlation of HVPG and PVP were analyzed, and explore their clinical value.

RESULTSThere is no significant agreement or correlation between HVPG and PVP in 5 patients, whose third hilar have large communicating branches between portal vein and Inferior vena cava, or with obvious umbilical vein opened. The HVPGs were significantly agreed with portal vein pressure in other 41 patients. There is no significant difference of HVPG or PVP between earlyTIPS and not early-TIPS groups. In addition, the portal vein pressures after TIPS were significantly decreased compared with that before TIPS.

CONCLUSIONThe HVPG can well show the PVP except these with obvious communicating branches between portal vein and Inferior vena cava in third hilar, and TIPS can effectively decrease the portal vein pressure in patients with portal hypertension.
