Selective delivery in a twin gestation, ,

One or more infants of a multifetal pregnancy occasionally require delivery selectively because of in utero risk of fetal death in circumstances in which the sibling fetus appears well. At 26 weeks 5 days of gestation a small fundally placed twin in a dichorionic gestation had an estimated fetal weight of 650 g with decreased amniotic fluid and ominous Doppler velocity findings in his umbilical artery. A normally grown presenting sibling had reassuring fetal surveillance data. Over a 2-week interval the growth-restricted twin showed no growth, and his status deteriorated. He was selectively delivered by hysterotomy. Selective delivery may offer parents of multifetal gestations an additional option when 1 or more of their fetuses are at high risk for in utero death.
