Patient's question:
Earlier, I had a non-invasive DNA test, and there were no abnormalities in chromosomes 13, 18, and 19. Today, I had a 3D ultrasound, and the doctor said it was a single umbilical artery, and the baby is a bit small. I searched online and found that babies with a single umbilical artery have a high risk of abnormalities. What should I do?Doctor's answer:
If the non-invasive tests you've done are all normal, the single umbilical artery usually doesn't cause much interference. The single umbilical artery simply means that normally there are two arteries, but one artery and two umbilical veins are present. You should pay attention to fetal movement regularly and have regular prenatal check-ups. You have already undergone non-invasive tests, and it is basically possible to determine if the fetus has any abnormalities. Now, if the 4D ultrasound shows no limb or organ structural abnormalities, there is no need to worry too much. There are also healthy babies with a single umbilical artery.
