Liver: venous dilation - ultrasound (color flow Doppler sagittal plane)

  1. Ascites with distended hepatic veins indicates elevated right atrial pressure or obstruction to the caudal vena cava (Budd-Chiari syndrome).
  2. The color flow Doppler sample box shows normal direction of blood flow in the hepatic veins (flow is away from the transducer and towards the caudal vena cava).
  3. Pulsed wave Doppler (not shown) can be used to measure velocity and direction of flow in the hepatic veins. With elevated right sided pressures there may be an increased reversal wave.
  4. The hepatic vein can be identifed by the presence of a thinner, less echogenic wall compared to the portal vein.
