Portal flow direction and velocity Usually, blood flow in the portal vein is hepatopetal (toward the liver) during the entire cardiac cycle. The mean velocity is 15-18 cm/s and varies with cardiac cycle. In PH, velocity fluctuations disappear, resulting in continuous flow.

A flow reversal (or a hepatofugal flow) is seen in the case of portal hypertension (Fig. 6). The portal vein is the primary route for blood to flow into the liver.It being patent means there's no clot and blood is flowing freely through the vessel. Interestingly, hepatopetal flow (systemic to portal shunting) may be seen in cases of IVC thrombosis. Patent Center Overview provides details on how to file an application in Patent Center.
