The vascular channel in the fetus passing through the liver and joining the umbilical vein with the inferior vena cava. [TFD][VHOG]
Ductus venosus naturally closes during the first week of life in most full-term neonates; however, it may take much longer to close in pre-term neonates. Functional closure occurs within minutes of birth. Structural closure in term babies occurs within 3 to 7 days. After it closes, the remnant is known as ligamentum venosum
