双胎中一胎儿死亡后的处理与胎儿死亡的时间有关。孕早期死亡胎儿症状自行消失,生存的胎儿预后良好。妊娠中期胎儿死亡后成为纸样儿,生存的胎儿有发生某些异常的危险。很多学者对妊娠末期的胎儿死亡进行了研究。1950年 Weiner 等首次报道胎儿宫内死亡导致母体凝血障碍。其后 Prit-chard 的研究表明:母体弥漫性血管内凝血(DIC)是由于来自死胎及其胎盘的凝血激酶进入母体所
The handling of a fetus in a twins is related to the time of fetal death. Early pregnancy fetal symptoms disappear on their own, the survival of the fetus a good prognosis. After the second trimester of pregnancy, the fetus becomes a pattern and the surviving fetus is at risk of some abnormalities. Many scholars have studied fetal death in late pregnancy.
