Second-trimester anhydramnios, which is primarily caused by ruptured membranes, placental dysfunction, or congenital renal malformations, is associated with high perinatal morbidity and mortality. Although amnioinfusion temporarily increases amniotic fluid volume, it does not generally provide a fundamental solution. We describe a case of second-trimester anhydramnios with an umbilical cord factor, wherein single amnioinfusion may have successfully broken a vicious circle involving non-reassuring fetal status. A 34-year-old primigravid woman was referred to our hospital because of anhydramnios at 22 weeks' gestation. Single amnioinfusion improved the fetal circulatory failure, and the patient delivered a healthy full-term newborn. Single amnioinfusion may be a therapeutic approach to improve the prognosis of pregnancy when second-trimester anhydramnios results from umbilical cord factors.
