Body was changed:

Hepatofugalis an abnormal flow pattern where the portal venous flow is from the periphery of the liver towards the porta and backwards along the portal vein. This phenomenon is not uncommon in patients with liver disease 3.

It is the opposite of hepatopetal.

Hepatofugal flow can be demonstrated on angiography, Doppler ultrasonography, magnetic resonance imaging, and / or CT/or CT. Doppler ultrasound however tends to be the best modality at quantifying this abnormality.

Pathology

Causes
  • cirrhosis with portal hypertension
    • considered the most common cause of hepatofugal flow in the portal venous system 3
    • usually tends to be continuous reversal rather than pulsatile reversal
    • indicates advanced portal hypertension 
    • cirrhotic patients with hepatofugal flow are thought to have greater hepatic dysfunction, a higher incidence of hepatic encephalopathy, variceal bleeding and higher higher mortality compared compared with cirrhotic patients with hepatopetal flow 5
    • can change back to hepatopetal flow after ingestion of food, which is considered to on the basis of a postprandial increase in splanchnic venous flow and portal venous flow, this phenomenon however may be blunted in patients with cirrhosis 3
  • triscuspid regurgitation - tends: tends to have reversed pulsatile flow (RPF) in portal vein.
  • arterio-portal fistula in liver
