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.

2021年9月15日 · 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.

2023年7月24日 · 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]

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 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.

2025年2月9日 · 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.

The ductus venosus (DV) is a temporary blood vessel that is part of the fetal blood circulation system and connects two large vessels. This small vessel pushes oxygenated blood from the umbilical vein into the inferior vena cava at its connection to the right upper part of …

What is the ductus venosus? The ductus venosus (DV) is a blood vessel that is only present before birth. It has the shape of a funnel and is situated between the umbilical vein, at the level of the liver, and the baby’s heart.

The ductus venosus is a physiological shunt and a regulating element of the pathway via sinistra that directs 20–30% of the well-oxygenated blood from the umbilical vein, via the inferior vena cava (IVC) and foramen ovale, to the left atrium, ensuring oxygenation of the …
