Chorionic edema can be caused by hyperemesis gravidarum, either complete or partial.
Staphylococcus is a relatively common trophoblastic disease of pregnancy, because after pregnancy, the placental chorionic trophoblastic cell proliferation, interstitial edema, the formation of different sizes of blisters, shaped like grapes, so it is called Staphylococcus, also known as blister-like fetal mass. Grape fetus can be divided into two types: complete and partial.
1. Complete hyperemesis gravidarum: the chorionic villi are in the form of blisters of varying sizes, which are connected by thin fibrils, mixed with blood clots and fragments of meconium. The blisters can occupy the entire uterine cavity, and the fetus and its appendages cannot be seen.
2. Partial hyperemesis gravidarum: only part of the villi are blistered, combined with embryonic or fetal tissue, but the fetus is mostly dead, often accompanied by fetal growth retardation or multiple malformations.
Consultation with a specialized doctor is recommended for specific cases.
