Patient's question:
NoDoctor's answer:
Fetal hydrops syndrome is a highly fatal fetal abnormality. It occurs in the fetus and early infancy, characterized by severe generalized edema of soft tissues, with significant fluid accumulation in the chest and abdomen, as well as enlargement of the heart, liver, and spleen. In severe cases, it can lead to fetal death or hemolysis and kernicterus after birth. The perinatal mortality rate is very high. Additionally, fetal hydrops, placental gigantism, and increased uterine tone can easily lead to severe complications in pregnant women, such as pregnancy-induced hypertension and postpartum hemorrhage.Fetal hydrops can be classified as immunologic or non-immunologic. Immunologic hydrops refers to immune hemolysis of the fetus or newborn caused by blood type incompatibility between the mother and fetus, which is a type of isoimmunization disease. It is primarily caused by ABO blood type incompatibility and Rh blood type incompatibility. Although the fetus has its own protective mechanisms, it is still essential for pregnant women to pay attention to regular prenatal examinations, blood type antibody screening, and ultrasound monitoring. It has been reported that the incidence of hemolytic disease caused by ABO blood type incompatibility accounts for approximately 2% to 2.5%, while Rh blood type incompatibility accounts for 5%.
