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.

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
- Decreased portal vein cross-sectional area^[1]

Color-Doppler ultrasound may be helpful in the diagnosis of portal hypertension. Findings on an color-doppler ultrasound suggestive of portal hypertension include:^[2]
- Increased diameter of left gastric vein
- Increased diameter of portal vein
- Increased flow velocity in left gastric vein

- Diameter and velocity in left gastric vein are significantly associated with incident of esophageal varices^[3]
