What a gravidarium looks like when it is born is closely related to the type of gravidarium, which may have no embryonic tissue or may be a dead or malformed fetus. There are two types of hyperemesis gravidarum: complete hyperemesis gravidarum and incomplete hyperemesis gravidarum. 1. Complete gravidarium: chorionic villi are in the shape of grapes, which are connected with the tips and named like grapes, there is no embryonic tissue, which can be diagnosed by ultrasound, and once diagnosed, it should be cleared in time, and if necessary, it can be cleared twice, and the blood level of β-hCG should be followed up regularly after the operation. 2. Incomplete hyperemesis gravidarum: some of the villi are in the form of grapes, but there are still some embryonic or fetal tissues and the fetus is mostly dead or accompanied by multiple malformations, and the combination of full-term infants is very rare. Vitreous fetus is caused by chromosomal abnormality of the embryo, so once the pregnancy is diagnosed, ultrasonography should be carried out in time to exclude the possibility of vitreous fetus; if diagnosed as vitreous fetus by ultrasonography, it is necessary to go to the hospital in time to consult the doctor and comply with the standardized treatment prescribed by the doctor, and do not take any action without authorization, in order to avoid the adverse outcome.
