Overview

Echo-Doppler may be helpful in the diagnosis of portal hypertension. Findings on an echo-doppler suggestive of portal hypertension include lack of increase in portal vein diameter in response to meals, increased portal blood flow velocity, and decreased portal vein cross-sectional area. Color-Doppler ultrasound may be helpful in the diagnosis of portal hypertension. Findings on an color-doppler ultrasound suggestive of portal hypertension include increased diameter of left gastric vein, increased diameter of portal vein, and increased flow velocity in left gastric vein. Biphasic and reverse flow in portal vein along with re-canalization of umbilical vein are pathognomonic for portal hypertension.
