Ducto venoso – Wikipédia, a enciclopédia livre

In the fetusthe ductus venosus Arantius’ duct after Julius Caesar Aranzi [1] shunts a portion of the left umbilical vein blood flow directly to the inferior vena cava. It is a part of fetal circulation.

The pathway of fetal umbilical venous flow is umbilical vein to left portal vein to ductus venosus to inferior vena cava and eventually the right atrium. This anatomic course conducti important in the assessment of neonatal umbilical venous catheterization, as failure to cannulate through the ductus venosus results in malpositioned hepatic catheterization via the left or right portal veins.


Ducto venoso

Complications of such positioning can include hepatic hematoma or abscess. The ductus venosus is open at the time of birth and is the reason why umbilical vein catheterization works. The 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. If the ductus venosus fails to occlude after birth, it remains patent openand the individual is said to have a patent ductus venosus and thus an intrahepatic portosystemic ee PSS.

The ductus venosus shows a delayed closure in preterm infantswith no significant correlation to the closure of the ductus ed or the cpnducto of the infant.
