The fetus does not turn into a gravidarium after termination, but may itself be a partial gravidarium, which contains fetal tissue from embryonic arrest. Vitellaria manifests itself as vaginal bleeding after menopause, and is the result of abnormal proliferation of placental chorionic trophoblasts and interstitial edema after pregnancy, forming blisters of varying sizes, which are connected to each other by their tips to form clusters, shaped like grapes. Grapes are a kind of abnormal pregnancy, which can be divided into complete hyperemesis gravidarum and partial hyperemesis gravidarum. In the former case, the blisters occupy the entire uterine cavity without the fetus and its appendages. The latter is only part of the chorionic villi are blistering, combined with the embryo or fetal tissue that has already been aborted, most of the developmental delay or malformation, the embryo is unable to develop normally, so it is easy to be confused with simple embryonic arrest, and it is necessary to rely on the pathological results of the uterus after the purging to make it clear. Therefore, the embryo will not turn into a gravidarium after the embryo has been terminated, usually it is a partial gravidarium itself, and see the blister-like gravidarium tissue combined with the terminated embryo.
