Is amniocentesis necessary for single umbilical artery?

Single umbilical artery is not uncommon in clinical practice. If a single umbilical artery is found, it is necessary to check whether there are abnormalities in the various systems of the fetus. In this case, a puncture examination is not necessarily required, because a single umbilical artery does not necessarily lead to fetal malformations. Therefore, pregnant women should not worry too much. You can have a B-ultrasound reexamination to see if there is any hypoxia, etc. Just strengthen good conditioning and don't worry too much.

Generally, the fetus's umbilical cord has two umbilical arteries and one umbilical vein. The fetus has only one umbilical artery and one vein, which is called a single umbilical artery. This phenomenon is relatively rare in humans, its mechanism of occurrence has not been fully elucidated, and its clinical significance is still under study. It is generally believed that a single umbilical artery is one of the signs of abnormal fetal development. However, the presence of a single umbilical artery alone does not indicate abnormal fetal development or chromosomal abnormalities. It just suggests that the probability of abnormalities is about ten times higher than that of a fetus with a normal umbilical cord. Mothers who are pregnant with a single umbilical cord and are moving should do a fetal malformation examination before 28 weeks and pay attention to fetal movements.

There is no way to intervene in a single umbilical artery, and the cause of its occurrence is currently unclear medically. It is a natural and accidental thing.

Usually single umbilical artery. Rule out problems in the three areas of fetal system B-ultrasound, fetal heart, and fetal chromosomes. Do these three checks well.

There will be no problem.

Single umbilical artery is included in the B-ultrasound examination items because of the risk factor and probability issues. It does not mean that babies with single umbilical artery have problems. The vast majority of babies born with a single umbilical cord are healthy. The problem with a fetus with a single umbilical artery is that the chance of abnormalities is about ten times higher than with a fetus with double umbilical artery, if all your tests are normal. Then the risk is about the same as that of an ordinary fetus.

If there is a problem, it will usually be discovered in the uterus. The baby's examination showed that everything was normal, and the probability of being born with deformities is not much different from that of a normal baby.

The main things to do for a single umbilical artery are to do a thorough examination, rule out developmental abnormalities, and do an ultrasound to screen for fetal malformations. At least two level three screenings should be done. One between 20-23 weeks and one between 28-32 weeks. It is also recommended to do a fetal cardiac ultrasound and [fetal echocardiogram] to rule out the possibility of congenital heart disease. Best done between 24-26 weeks. It is best not to exceed 28 weeks. If conditions permit, it is also recommended to do fetal chromosome testing. If everything is normal, just wait for delivery with peace of mind.
