Having a history of fetal arrest and getting pregnant again usually does not require immediate fertility preservation, and patients who have symptoms of preeclampsia can be treated with fertility preservation. There are more reasons for embryonic arrest, such as chromosomal abnormality of the embryo itself, maternal factors, environmental factors, etc. A single arrest does not necessarily mean that the patient is suffering from a certain part of the disease. Therefore, getting pregnant again after a single fetal arrest does not need to be preserved at the beginning. However, if the patient experiences vaginal bleeding, abdominal pain and other symptoms during the course of the pregnancy, it is recommended that progesterone be given to preserve the pregnancy. However, not all cases of fetal arrest do not require early abortion preservation. If it is clear that the arrest in the previous pregnancy was caused by insufficient luteal function of the pregnant woman, abortion preservation treatment can also be carried out when the second pregnancy has not yet developed symptoms. If a patient has a second pregnancy after a fetal arrest, the patient should follow the doctor’s instructions for treatment and labor and delivery tests.
