After embryonic arrest occurs, it is necessary to handle it promptly, which involves expelling the embryo from the body. If the embryo remains for an extended period without timely intervention, it can easily lead to an infection in the uterine cavity, or even sepsis. The fetus may adhere to the uterine wall, making it difficult to clean later and can easily cause severe bleeding, seriously endangering the patient's life.

Therefore, once we identify that an embryonic arrest has definitely occurred, it is crucial to undergo prompt uterine cleaning treatment. It is advisable to communicate with the hospital doctors and take appropriate measures.

Will the embryo still grow if the embryo has ceased development?

Embryo arrest, also known as missed abortion, refers to the condition in early pregnancy where, due to congenital developmental defects in the gestational sac or other influencing factors, natural development does not occur, resulting in the absence of a fetal heartbeat. Once embryo arrest has been diagnosed, the embryo generally does not continue to grow, because embryo arrest means that the gestational sac has died and is gradually decaying. If a subsequent ultrasound check reveals that the embryo may have grown slightly since the previous examination, this should not be considered as growth continuation of the embryo, but rather attributed to measurement error. Therefore, once embryo arrest is detected and meets diagnostic criteria, timely re-examination may show some lengthening of the embryo. However, in the absence of a fetal heartbeat, it still needs to be treated as embryo arrest, and an abortion procedure should be promptly performed.

Does embryonic arrest definitely require a uterine curettage?

After embryo arrest, it is necessary to terminate the pregnancy in a timely manner, but it is not always necessary to undergo a uterine curettage; medication can also be taken orally to help expel the pregnancy sac. Oral medication can stimulate the uterus and soften the cervix to cause uterine contractions and expel the pregnancy sac outside the uterus. However, if the embryo arrest occurs later in the pregnancy, then an artificial abortion is required, which can be done by direct curettage or uterine clearing to help expel the pregnancy tissue. Therefore, it is recommended to go to the hospital for an ultrasound examination after embryo arrest, and then decide whether to choose medical abortion or uterine clearing based on the timing of the examination. (The specific medication should be taken under the guidance of a doctor.)

Do you need to be hospitalized for uterine evacuation after a missed miscarriage?

The criteria for diagnosing embryo arrest generally involve the appearance of the embryonic bud and heart tube between six to eight weeks. If these are not visible beyond eight weeks, the situation is referred to as embryonic arrest. Embryonic arrest requires abortion, which for safety reasons typically involves hospitalization and a combination of medication and uterine evacuation. However, if the gestational sac is relatively small, an outpatient abortion procedure might be sufficient. Whether hospitalization is necessary should be assessed by a doctor, who will consider factors such as previous scar pregnancies, the condition of a scarred uterus, and the size of the current gestational sac, to make a comprehensive decision.

Embryonic arrest means

Embryonic arrest, as the name implies, refers to the cessation of embryo development. In clinical practice, it is also called fibroid miscarriage. Embryonic arrest is a pathological condition. Normally, in the early stages of pregnancy, as activity increases, the gestational sac gradually begins to show a yolk sac, embryo bud, and fetal heartbeat. If the fetal heartbeat is still not visible after a certain period, it indicates that the gestational sac is in a state of decay and that the embryo has stopped developing. Generally, 9 weeks of pregnancy is considered the final deadline for diagnosis. If no fetal heartbeat is detected during an ultrasound at 9 weeks of pregnancy, it can be diagnosed as embryonic arrest. Once diagnosed, it is advisable to proceed with an abortion as soon as possible to minimize harm to the woman’s body. If embryonic arrest occurs consecutively more than twice, a thorough examination of both partners should be conducted to determine the cause, to guide the next pregnancy.

Do you need to be hospitalized for a miscarriage due to embryonic arrest?

In cases where there is an embryo arrest, an abortion generally does not require hospitalization. However, if the embryo arrest occurs after three months, then hospitalization is necessary for treatment. For pregnancies of shorter duration, within 50 days, it is usually possible to induce abortion with medication. But if it exceeds 50 days and is within 70 days, a painless surgical abortion can be performed to manage the condition. This scenario generally does not require hospitalization and can be handled in an outpatient gynecological clinic. However, for longer-term pregnancies, there may be complications during the abortion process, and it is advisable to be hospitalized for treatment.
