Delayed interval delivery in twin pregnancy - case reports.

The implementation of assisted reproduction has increased the incidence of multiple pregnancies. Prenatal death of one fetus in the second trimester of twin pregnancy confronts the obstetrician with a difficult problem with regard to the management of pregnancy. The scarcity of the condition and the absence of the large-scale studies make it difficult to advise the parents on the prognosis and optimal management. The unavoidable birth or death of one premature neonate has led to the aim of delayed interval delivery for the other twin. We present in this report two cases of twin pregnancies with delayed-interval delivery and favorable outcomes for the surviving twins. The twin pregnancies conceived by in vitro fertilization (IVF) in HitMed Medical Center, Craiova, Romania. In the first case, one fetus dismiss in utero at 20 weeks of gestation. The second fetus was successfully delivered by Caesarean section, at 36 weeks. In the second case, the first fetus was delivered at 22 weeks. To save the surviving fetus, ligation of the umbilical cord at the cervical level was performed. The second fetus was delivered at 31 weeks by Caesarean section, in good conditions. We describe our management of the cases and the deliveries and the neonatal outcomes. In multiple gestation, prolongation of pregnancy after preterm dismiss in utero or even after delivery of one fetus is feasible in a closely monitored environment.
