Hepatopetal denotes flow of blood towards the liver, which is the normal direction of blood flow through the portal vein. The term is typically used when discussing the portal vein or recanalized vein of the ligamentum teres in patients with suspected portal hypertension.
Hepatopetal denotes flow of blood towards the liver, which is the normal direction of blood flow through the portal vein. The term is typically used when discussing the portal vein or recanalized vein of the ligamentum teres in patients with suspected portal hypertension. It is the opposite of hepatofugal.
Portal venous flow is approximately 1150 ml/min, as opposed to hepatic arterial flow, which is only 350 ml/min, resulting in total liver blood flow of 1500 ml/min. The portal vein supplies between 50 and 70% of the oxygen to the liver, especially during the fasting state.
Hepatofugal or non-forward portal flow (NFPF) is an abnormal flow pattern in which the portal venous flow is from the periphery of the liver towards the porta hepatis and backwards along the portal vein. This phenomenon is not uncommon in patients with liver disease 3.
Patent track sign is a finding on color Doppler ultrasound, representing blood traveling along the course a biopsy needle track. It can occur after a biopsy of any organ, but is more often seen after liver or kidney biopsies.
A normal portal venous flow is hepatopetal. A flow reversal (or a hepatofugal flow) is seen in the case of portal hypertension (Fig. 6).
The overall mortality rate of the patients with hepatofugal portal venous flow was 26.67% (95% confidence interval, 11.1%–42.9%). Causes of death were multiorgan failure with septic or hypovolemic shock (n = 5), hepatic failure (n = 2), and cardiac failure (n = 1).
