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.
