2. Retrograde flow in early diastole
3. Sharp systolic upstroke
4. A high resistance waveform

Q

Sonographic findings commonly associated with portal hypertension include which of the following?
1. Hypoechoic liver parenchyma and gastric varices
2. Splenomegaly and hepatofugal flow in the main portal vein
3. Hyperechoic liver parenchyma and hepatopetal flow in the main portal vein
4. Splenomegaly and decreased resistance in the proper hepatic artery

A
  1. Portal hypertension is associated with compression or occlusion of the portal veins. Sonographic findings findings may include
  2. Hepatomegaly,
  3. Splenomegaly
  4. Hepatofugal flow in the hepatic artery
  5. Formation of collaterals
  6. Increase in diameter of the MPV, SV, and SMV.

Echogenicity of the liver parenchyma is generally hyperechoic. Hypoechoic liver parenchyma is more likely associated with hepatitis.

  3. hyperechoic to the pancreas
  4. Hyperechoic to the renal sinus
