A woman is not able to continue her pregnancy after a fetal arrest and cannot wait another week. Fetal arrest generally refers to embryonic arrest. When embryonic arrest occurs, the dead embryo, if retained in the uterus for a long period of time, and the embryo dies for a long time, can make the embryonic tissue and the uterine wall tightly adhered and difficult to separate. At the same time, due to the lack of sex hormones, the uterine contraction ability decreases, it is not easy to expel the embryo out of the body, and in serious cases, it can also lead to the mother’s coagulation dysfunction, resulting in uncontrollable and serious bleeding, which can be a crisis of the pregnant woman’s life. Therefore, after the embryo has stopped, it is not possible to wait for another week or a long time to stay in the uterus. Patients with embryonic sterilizations need to be handled promptly once diagnosed, and appropriate methods are chosen to terminate the pregnancy on the basis of safeguarding the safety of the pregnant woman. The most common method is the removal of the uterus. Generally speaking, when the diagnosis of embryonic arrest, the patient should consult the doctor in time, and actively take appropriate treatment measures, not blindly wait, so as not to delay the condition, resulting in serious effects.
