Retained miscarriage, which can usually be reported through embryopathology, may result in hyperemesis gravidarum, or other trophoblastic diseases.
Retained miscarriage, also known as second trimester miscarriage, is a specific type of spontaneous abortion in which the embryo or fetus is retained in the uterine cavity after death and is not expelled naturally in a timely manner. The causes of induced abortion include embryonic factors, maternal factors, paternal factors and environmental factors.
It is usually possible to distinguish whether the state of miscarriage is the result of a normal pregnancy followed by an abortion or a chromosomal abnormality of the fertilized egg, placental trophoblasts, and other causes such as gravidarium, erosive gravidarium, and choriocarcinoma by the pathology report of an indeterminate miscarriage. Staphylococcus is a benign disease, while the others, erosive staphylococcus and choriocarcinoma, are malignant.
Early-stage induced abortion requires early curettage; late-stage induced abortion can expel the contents of the uterine cavity naturally after contractions are induced, and if unsuccessful, removal of the uterus can be performed; attention also needs to be paid to the prevention of disseminated intravascular coagulation and infections.
