2019年8月30日 · 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. History and etymology

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 .

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5月11日 · A pulsatile portal venous flow pattern is an abnormal form of portal venous flow and can result from both physiological and pathological causes. In well subjects, mild to marked pulsatility has been described.

2024年4月25日 · The portal vein (PV) (sometimes referred to as the main or hepatic portal vein) is the main vessel in the portal venous system and drains blood from the gastrointestinal tract and spleen to the liver.

2024年8月28日 · Cavernous transformation of the portal vein is most of the times inefficient in guaranteeing adequate portal vein inflow to the liver parenchyma far from the hilum and, therefore, is associated with an increased hepatic arterial flow to those peripheral liver segments.

2023年8月22日 · Coarsened hepatic echotexture is a sonographic descriptor used when the uniform smooth hepatic echotexture of the liver is lost. This can occur due to a number of reasons which include: conditions that cause hepatic fibrosis 1 cirrhosis hemoch...

2025年1月8日 · When performing a hepatic CT protocol, the occlusion of a branch of the portal vein by a thrombus can manifest as transient hepatic attenuation differences (THAD) in the arterial/early portal phase, showing increased enhancement (i.e. perfusion) of the lobe or segment previously supplied by the vein due to hepatic arterial compensatory flow.

2024年8月15日 · Portal vein embolization (PVE) is a technique used to selectively occlude the blood supply to one of the liver lobes, diverting portal blood flow to the other lobe, the future liver remnant (FLR). This diversion will increase the size of the post-hepatectomy future liver remnant, which improves surgical outcomes by preventing liver insufficiency.

Hepatic congestion due to right heart failure and/or triscuspid regurgitation is a prominant feature and a reflection of elevated right atrial pressure. Secondary flow changes can occur in the portal vein and its branches reflecting the high pulstaile hepatic venous pressure waves.
