Fetal malformations are suspected at 34 weeks of pregnancy and require further examination. If the examination is clear that there are fetal malformations, the choice of whether to end the pregnancy is based on the malformation and the family’s own wishes. Tests to detect fetal malformations during pregnancy are usually performed in the early to mid-pregnancy, such as fetal nuchal translucency thickness, Down’s syndrome, non-invasive DNA, amniocentesis, 3D or 4D ultrasound, etc. If fetal malformations are suspected by 34 weeks of pregnancy, ultrasound can be performed to clarify whether there are fetal malformations. What ultrasound can usually detect is a structural abnormality in the fetus. If a fetal abnormality is detected, the decision to end the pregnancy will be based on the extent of the abnormality’s impact on the child’s future growth and the family’s wishes. It is important for pregnant women to have regular checkups, and if there are any abnormalities in the test results, they need to seek medical advice and treatment under the guidance of a doctor.
