We retrospectively evaluated a series of 18 monoamniotic and 7 pseudomonoamniotic (secondary to rupture in the membrane dividing monochorionic diamniotic twins) twin gestations managed after 20 weeks' gestation. There were no significant differences in the incidence of neonatal death or umbilical cord entanglement between the monoamniotic and pseudomonoamniotic twin gestations (33 versus 21%, P = 0.94 and 72 versus 43%, P = 0.36). Therefore, the same serious management may be needed for pseudomonoamniotic twin gestations as for monoamniotic twin gestations.
我们回顾性评估了一系列在妊娠20周后接受管理的单羊膜囊双胎妊娠(18例)和假单羊膜囊双胎妊娠(继发于单绒毛膜双羊膜囊双胎之间的胎膜破裂,共7例)。单羊膜囊双胎妊娠和假单羊膜囊双胎妊娠的新生儿死亡发生率或脐带缠绕发生率无显著差异(分别为33%对21%,P = 0.94;72%对43%,P = 0.36)。因此,假单羊膜囊双胎妊娠可能需要与单羊膜囊双胎妊娠同样严格的管理。
