What Is Ductus Venosus And What Does It Do
Oxygen to brain: In the fetus, the ductus venosus shunts approximately half of the blood flow of the umbilical vein directly to the inferior vena cava. Thus, it allows oxygenated blood from the placenta to bypass the liver. In conjunction with the other fetal shunts, the foramen ovale and ductus arteriosus, it plays a critical role in preferentially shunting oxygenated blood to the fetal brain. ...Read more

It should be evaluated by cardiologist and may be closed through a catheter and not require surgery. Foramen Ovale (Communication between R/ L upper chambers of heart) normal at birth and stays open in ~25% of people.Rarely a problem . ...Read more
My right ductus deferen is swollen. When looking from above i can see a small bump. The pain is not always consistent. Can you please help?

Causes the PDA: The PDA is a critical vessel that allows the blood to bypass the lungs and get to the placenta while babys are still inside, in mom's uterus. The lungs are full of amniotic fluid and don't do any gas exchange (o2 delivery and co2 release) eveyone is born with a pda, it persists... Open (patent) most commonly in premature babies. There is no absolute answer as to why it stays open in some people. ...Read moreSee 1 more doctor answer
Size Matters in PDAs: A tiny, "silent ductus" is essentially one that can be ignored. No restrictions! other pdas may cause mild inefficiency in the work of the heart. Kids will get tired sooner than if they didn't have this pda. This isn't dangerous. However, i would not hesitate to close a PDA in the cath lab by coil or device embolization. It is a relatively low risk cath procedure. Outpatient or overnight stay. ...Read moreSee 2 more doctor answers
Device closure: Pdas can almost always be closed in the catheterization laboratory using a small metal coil or device that can be placed with a catheter placed in the vein or artery in the groin rather than a surgery. In premature infants, it can often be closed with a medication. If this fails, surgery is most often done since they are too small for catheter-based methods. Soon there may be smaller systems. ...Read moreSee 1 more doctor answer
