I have a condition called single umbilical artery(sua). Are there any risk on my pregnancy or any bad effects on my baby after delivery?

Confusing question: You ? Had a sua or the baby ? This is a variable finding that most often turns out to be an innocent incidental finding.A subgroup of patients will have chromosome defects or genetic syndromes, with other obvious anomalies. If this has not affected you so far, i would not expect any issues with the baby.Consult a geneticist affiliated with a children's hospital or medical school to gain more info. ...Read more

What is sua (single umbilical artery)?

Single artery: Usually in the umbilical cord there are two arteries and one vein. Every now and then a baby is born with one artery in the umbilical cord. In the majority of cases this is not a problem. That single artery can support the pregnancy. Occasionally the single artery can indicate the presence of a congenital abnormality of heart, kidney, intestines. This can be identified by ultrasound. ...Read more

Did a SUA (single umbilical artery) cause my baby to die?

Doubtful: Many infants are born with a single umbilical artery and have an uncomplicated life. For some, it is just one of many abnormalities that are part of a complex pattern or syndrome, and could be part of a chromosome defect. I encourage parents to have a full workup done on infant deaths so they can understand what happened, and any implications for future pregnancies. ...Read more

25weeks pregnant with twins and baby a has a single umbilical artery. Should i be concerned?

Maybe: Single umbilical artery does not necessarily pose a risk to you or your child as an umbilical cord with just one artery is sufficient to support a pregnancy to term. However, sua does increase your child’s risk for certain birth defects. Talk to your OB about this and see if you need additional workup.... ...Read more

Hi doctor, I am 6 months pregnant with twins.One of my twin is found to have single umbilical artery in the anomaly scan. Is there any prob wit this?

Maybe: Single umbilical artery occurs in up to 1% of all pregnancies. In 25%, the baby may have abnormalities of the heart, skeletal system, and kidneys among other things. Your doctor may want to send you for a higher level ultrasound study for a more intensive fetal survey evaluation. If other problems are found then genetic counseling is often obtained .Remember, in 75% there are no problems. ...Read more

Epigenics & C.H.D. had local anæsthetic near my ankle during 1st few weeks of pregnancy. Fetus had single umbilical artery. Born with COA. Connection?

Highly unlikely: lidocaine is not a known teratogen, very well documented. A single umbilical artery and other birth defects including coarctation of the aorta may have genetic cause.. Is your baby female? A clinical genetics consult is indicated, as you deserve genetics counseling and testing. Contact your local clinical geneticist, or you may ask for a live consultation through Healthtap. ...Read more

What happens to the veins or arteries in the umbilical cord that were connected to the baby (the baby's end)?

What happens to the veins or arteries in the umbilical cord that were connected to the baby (the baby's end)?

Not needed any more!: The two arteries and vein that are in the cord, as well as the supporting gelatinous-like substance that surrounds those vessels, pretty much just 'shrivel up'. (in the womb, they carried blood to and from the placenta.) it isn't unusual to see a very small amount of blood as the dried stump of the cord separates, and even a few days after that, but there shouldn't be any other kind of discharge. ...Read more

Arteries: higher pressure, thicker walls, stretch (pulse) with each heart contraction & deliver blood to the arterioles which control the flow to individual capillaries. Veins are blood vessels which carry blood from capillaries back to the heart (body to right heart; ...Read more
