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.
