Multifetal pregnancies are at high risk for preterm delivery. Under certain circumstances, delayed vaginal delivery of the second twin is performed to improve morbidity and mortality. Most of the information on optimal management of delayed-interval delivery comes from published case reports in which the first twin was delivered vaginally. This case report is unique in that twin A was delivered via cesarean section.
CASE REPORT: Our patient was a 21-year-old G2P1, with dichorionic diamniotic twins of unknown gestational age, with prenatal care at a different facility, who presented with preterm prelabor rupture of membranes and cord prolapse. Twin A, with an estimated weight by ultrasound of 528 g, was delivered via cesarean section and twin B was left in utero until the patient went into preterm labor 10 days later. Obstetrical management included tocolytic protocol from the Management of Myelomeningocele Study trial, preterm prelabor rupture of membrane antibiotics with broad-spectrum coverage, and judicious use of fetal lung maturity steroids and magnesium sulfate.
CONCLUSIONS: This case is important as we have demonstrated that cesarean section in the setting of delayed-interval delivery may be an option to improve survival at the limits of viability. We also discussed our treatment approach and how we delayed delivery of the second twin by 10 days. Unexpectedly, the surviving twin was the one born first, at 22 4/7 weeks determined 2 days after birth by prenatal records.
