Three cases of a vanishing twin are reported. We observed twin pregnancies in three women, who had their ultrasound examination before the 10th week of pregnancy. Positive heartbeat was registered in both embryos. When a further sonographic examination took place at the 11th week, intrauterine death of one of the embryos was observed. All three pregnancies continued as singleton pregnancies to uneventful term deliveries. When the placentae and chorionic membranes were examined after delivery, small nodular pigmented areas were observed. Histological examination showed the remains of the embryo, who had vanished in the first trimester of pregnancy.
本文报告了三例消失双胎的病例。我们观察了三名女性的双胎妊娠情况，她们在妊娠第10周前进行了超声检查，两个胚胎均记录到了胎心。在第11周进行进一步超声检查时，发现其中一个胚胎发生了宫内死亡。所有三例妊娠均继续作为单胎妊娠，直至顺利足月分娩。产后检查胎盘和绒毛膜时，发现了小的结节状色素沉着区域。组织学检查显示了在妊娠早期消失的胚胎的残留物。
