intrauterine fetal demise
Death of a fetus in the uterus after 20 weeks of gestation, also known as stillbirth.
Full Definition
Intrauterine fetal demise (IUFD) refers to the death of a fetus in the uterus at or after 20 weeks of gestation, though some definitions use 22-24 weeks as the threshold. This condition affects approximately 1 in 160 pregnancies in the United States. Causes include placental abnormalities, fetal genetic disorders, maternal medical conditions, infections, and umbilical cord accidents. In many cases, the cause remains unknown despite thorough investigation. Management involves counseling, evaluation for underlying causes, and delivery planning, which may include induction of labor or cesarean section depending on individual circumstances.
Usage
Usage note: Use 'intrauterine fetal demise' in formal documentation rather than 'stillbirth'.
