Many malformations occur in late pregnancy.

The fetus may be deformed during pregnancy. Many people know that it is necessary to carry out a major fetal abnormality examination during pregnancy, so as to prevent the occurrence of deformed fetuses in time. In fact, many deformities occur in the early stages of pregnancy, but they may not be discovered until the late stages of pregnancy. So many people ask, do many deformities occur in late pregnancy?

Do many deformities occur in late pregnancy?

Generally, deformities are most likely to occur in the early stages of pregnancy. During this period, the fetus is most susceptible to external factors, but it may not be discovered in the early stages and regular examinations are required to determine the cause.

suggestion:

1. Generally, a four-dimensional color ultrasound examination will be performed at 22-26 weeks of pregnancy to observe whether there are any abnormalities in the growth and development of the fetus's internal organs.

2. The purpose of the current examination is to further observe the condition of the fetus, the amniotic fluid of the pregnant woman, and the embryo, which will provide guidance for the next step of production. During the entire pregnancy, each stage has its own development status. In the late pregnancy, growth and development are also of utmost importance. In the later stages of pregnancy, regular prenatal checkups and fetal heart rate monitoring are essential. Pay close attention to the growth and development of test tube embryos.

When should fetal anomaly screening be done?

Generally, color Doppler ultrasound can be done around 18-24 weeks of pregnancy to screen for antenatal abnormalities. Pregnant women usually go to the hospital for examination at 20 weeks of pregnancy, and it is best not to exceed 28 weeks of pregnancy. Because the fetus is in the rapid development stage of the brain around 24 weeks, the structure of the fetus at this stage has been formed, the size of the fetus and the amniotic fluid are appropriate, the activity space in the uterine cavity is large, the echo effect of the fetus's bones is small, and the image is clearer.
