2022年10月25日 · 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.

2024年11月24日 · Specific signs of hepatofugal flow, include: •Reversed Portal Vein Flow: Identified on Doppler ultrasound •Collateral Circulation: Seen on CT or MRI as varices or shunting vessels. •Splenomegaly: An enlarged spleen often accompanies portal hypertension, a common cause of hepatofugal flow.

2024年7月8日 · Portal venous flow is normally towards the liver (hepatopetal), with the normal main portal vein peak systolic velocities usually measuring 20-40 cm/s 1,3. The mean flow velocity of portal vein in adults is 19.3 cm/s 6 .

2002年1月1日 · Hepatofugal flow (ie, flow directed away from the liver) is abnormal in any segment of the portal venous system and is more common than previously believed. Hepatofugal flow can be demonstrated at angiography, Doppler ultrasonography (US), magnetic resonance imaging, and computed tomography (CT).

This article discusses the different characteristic flow patterns observed from the portal vein, hepatic artery, and hepatic vein in patients with liver cirrhosis or related complications and procedures.

Diffuse hepatofugal blood flow is in an indicator of portal hypertension. The most frequent cause is liver cirrhosis but other etiologies such as congestive heart failure and acute liver failure can be responsible for the same ultrasound findings.

2024年11月23日 · •How it works: Doppler ultrasound measures the flow of blood within the portal vein. It provides information about the size, shape, and flow direction of the blood vessel. •Key findings: •Normal blood flow in the portal vein is hepatopetal (toward the liver).

2024年11月24日 · Hepatopetal flow describes the normal direction of blood flow within the portal vein—flowing toward the liver. Imaging tests are important in detecting abnormalities of flow so that a prompt diagnosis can be made.

2023年10月2日 · Portal vein thrombosis (PVT) was defined as complete occlusion of the main trunk of portal vein with or without cavernomatous transformation or partial occlusion (<50% or ≥50%). Clinically significant HE was defined as the occurrence during follow-up of at least West-Haven grade 2 or higher HE.

2002年1月1日 · Hepatofugal flow (ie, flow directed away from the liver) is abnormal in any segment of the portal venous system and is more common than previously believed. Hepatofugal flow can be...
