Doppler hemodynamic study in portal hypertension and hepatic encephalopathy.

Abstract

Ultrasonographic parameters of portal hypertension show significant correlation between the diameters of liver/portal vein and spleen/splenic vein. Portal hemodynamic parameter (blood flow velocity) is significantly related to the stages of liver damage, presence of ascites and HE, while splenic hemodynamics is specific and not directly related to these parameters.
