Monoamniotic twin pregnancy involves a heavy risk of fatal umbilical cord entanglement. Two cases are reported. In the first case, both twins were found dead in the 36th week, and the monoamnionicity was recognized at birth. In the second case, the monoamnionicity was discovered during an ultrasound examination, and cord entanglement was suspected in the 35th week on the basis of a non-stress test (NST) with variable decelerations. Cesarean section was performed and two healthy children were delivered.
单羊膜囊双胎妊娠存在严重的致命性脐带缠绕风险。本文报告了两例病例。第一例中，两个胎儿均于孕36周时被发现死亡，单羊膜囊情况在出生时才被识别。第二例中，单羊膜囊情况在超声检查时被发现，在孕35周基于无应激试验（NST）出现变异减速而怀疑有脐带缠绕。随后实施了剖宫产，娩出了两名健康婴儿。
