fetal reduction
Procedure to reduce the number of fetuses in a multiple pregnancy to improve outcomes.
Full Definition
A procedure performed in multifetal pregnancies to selectively reduce the number of viable fetuses, typically from triplets or higher-order multiples to twins or singletons. The procedure aims to reduce maternal and perinatal complications associated with high-order multiple pregnancies, including preterm birth, growth restriction, and maternal morbidity. Fetal reduction is usually performed in the first trimester using ultrasound guidance and involves injection of potassium chloride into the fetal heart. The decision requires careful counseling about risks, benefits, and ethical considerations.
Usage
