Premature birth
Premature birth refers to delivery between 28 and 37 weeks of gestation. The newborn delivered at this time is called a premature infant. During premature labor, pregnant women may experience sensations such as lower abdominal distension and pain, and some may have a small amount of vaginal bleeding or fluid discharge.

Placenta previa refers to the placenta attaching to the lower uterine segment or covering the internal cervical os (blocking the normal exit for fetal delivery) after 28 weeks of gestation, with its position lower than the presenting part of the fetus. Its danger lies not only in obstructing normal fetal delivery but also in being one of the main causes of late pregnancy bleeding. It is a severe complication of pregnancy, characterized by sudden onset and rapid progression, and improper management can endanger the lives of both mother and fetus. The main symptom is recurrent, painless vaginal bleeding without an apparent cause.
View detailsTwin-to-twin transfusion syndrome
Twin-to-twin transfusion syndrome (TTTS) is a severe and unique complication of monochorionic-diamniotic twin pregnancies. It refers to a series of pathophysiological changes and clinical symptoms caused by one fetus (donor twin) continuously transfusing blood to the other fetus (recipient twin) within the uterus. It typically occurs between 15 and 26 weeks of gestation, and if left untreated, the risk of fetal death is over 90%. Pregnant mothers generally do not have specific symptoms other than those related to pregnancy. However, the clinical manifestations in the fetuses vary greatly depending on their blood volume. For example, if one fetus is the donor twin, its blood volume is significantly reduced, which can lead to oligohydramnios, oliguria, anemia, and intrauterine growth restriction. If the other fetus is the recipient twin, its blood volume is significantly increased, which can lead to polyhydramnios, polyuria, edema, and heart failure.
Fetal congenital malformation
Fetal congenital malformations refer to abnormalities in the morphology of a certain structure or organ of the fetus during its development. Common fetal malformations include anencephaly, hydrocephalus, open spina bifida, cleft lip, cleft palate, congenital heart disease, and Down syndrome (Trisomy 21). When fetal malformations occur, the mother usually has no subjective symptoms. The vast majority of fetal malformations can be detected by prenatal ultrasound examination.
