There are many things that women need to pay attention to during pregnancy. In addition to supplementing nutrition reasonably, they also need to regulate their emotions and undergo pregnancy tests on time. Some women are worried about the presence of a single umbilical artery during pregnancy tests and want to know the impact of a single umbilical artery on the fetus?
Single umbilical artery refers to the phenomenon where there is only one umbilical artery and one umbilical vein within the fetal umbilical cord. The appearance of a single umbilical artery can interfere with the normal supply of blood during embryonic development, which may lead to abnormal development of many systems in the fetus, such as the central nervous system, cardiovascular system, skeletal system, etc. In addition, it may also cause abnormal development of the fetal limbs. Therefore, it is important to pay attention to prenatal examinations.
If a single umbilical artery is found, pregnant women should also be careful not to worry too much. The main thing is to do a good job of examination, rule out abnormal development, and perform ultrasound screening on time. Third level screening also requires testing, which needs to be done twice or more, and the timing should be well controlled, with one between 20 and 23 weeks and the other between 28 and 32 weeks.
It is also recommended to undergo fetal cardiac ultrasound and fetal echocardiogram, through which the possibility of congenital heart disease can be ruled out. The timing should also be well controlled, with the best results occurring between 24-26 weeks of pregnancy and not exceeding 28 weeks. If conditions permit, it is recommended to undergo fetal chromosome examination. As long as everything is normal, pregnant women can proceed with labor with peace of mind.
