Embryonic arrest refers to the lack of natural development of the gestational sac in early pregnancy, characterized by the absence of a fetal heartbeat. If there is still no fetal heartbeat or embryo detected during an ultrasound at 8-9 weeks of pregnancy, it should be diagnosed as embryonic arrest. After embryonic arrest occurs, the vast majority require medical intervention. Of course, some cases of embryonic arrest can resolve naturally, leading to a miscarriage. However, this is not a reliable occurrence and is relatively rare in clinical practice. Moreover, the longer the wait, the greater the potential harm to the woman's health. For embryonic arrest, once diagnosed, it is urgent to intervene medically to remove the gestational sac from the uterus, minimizing harm to the woman. Common methods include medical abortion or a dilation and curettage surgery, either of which can be chosen.
