Background:
Fetal head entrapment during delivery is a rare occurrence in modern obstetrics. We present a case of intrauterine head entrapment of a second twin by a uterine synechia diagnosed by ultrasound and subsequent complications that occurred.
Case:
A woman with a twin intrauterine pregnancy presented at 19 weeks for evaluation of a shortened cervix. Ultrasound examination demonstrated fetal head entrapment of twin B by a uterine synechia, as well as intrauterine growth restriction (IUGR). The patient experienced preterm premature rupture of membranes at 24 weeks' gestation and underwent a cesarean delivery for a nonreassuring fetal heart rate tracing of twin B, with findings of a constricting band of fibrous tissue around the neck of twin B.
Conclusion:
Uterine synechia might cause intrauterine head entrapment and IUGR.
