In the fetus, the ductus venosus ("DV"; Arantius' duct after Julius Caesar Aranzi [1]) shunts a portion of umbilical vein blood flow directly to the inferior vena cava. [2] Thus, it allows oxygenated blood from the placenta to bypass the liver.

Jul 24, 2023 · The ductus venosus is a shunt that allows oxygenated blood in the umbilical vein to bypass the liver and is essential for normal fetal circulation.[1] Blood becomes oxygenated in the placenta and travels to the right atrium via umbilical veins through the ductus venosus, then to the inferior vena cava.[1]

Sep 15, 2021 · Ductus venosus (DV) is a narrow, trumpet-shaped vessel which is seen in the fetal liver connecting the umbilical vein directly to the caudal inferior vena cava or distal left hepatic vein.

The ductus venosus is a vascular shunt situated within the fetal liver parenchyma, connect-ing the umbilical vein to the inferior vena cava. This vessel acts as a bypass of the liver microcircula-tion and plays a critical role in the fetal circulation.

4 days ago · The ductus venosus describes the vitelline blood vessel lying within the liver that connects (shunts) the portal and placental (umbilical) veins to the inferior vena cava and also acts to protect the fetus from placental over-circulation.

In the fetus, the ductus venosus is a vascular channel that allows oxygenated blood to bypass the liver and flow directly to the inferior vena cava. A flow velocity pattern in the ductus venosus (DV) demonstrates the pressure gradient between the fetal umbilical vein and the right atrium.

Ductus venosus is a cone like canal with narrowed part which connects with the umbilical vein, and the wider which releases blood into the vena cava inferior. The majority of blood enters the ductus venosus even though there is another way, through port vein to the VCI.

The ductus venosus is a fetal vessel that functions importantly in the transfer of oxygen-and nutrient-rich blood from the umbilical vein to vital organs. Its control under active regulation and its anatomy result in a flow-velocity profile that is typically forward throughout the cardiac cycle.

The ductus venosus is a shunt that allows oxygenated blood in the umbilical vein to bypass the liver and is essential for normal fetal circulation. Blood becomes oxygenated in the placenta and travels to the right atrium via umbilical veins through the ductus venosus, then to …

The ductus venosus arantii, named after the Italian anatomist Giulio Cesare Aranzi (1530–1589), is a venous fetal intrahepatic shunt connection from the left portal vein to the inferior vena
