试管婴儿是体外受精-胚胎移植技术的俗称,是分别将卵子和精子取出后,置于培养液内使其受精,再将胚胎移植回母体子宫内发育成胎儿的过程.

In vitro fertilization (IVF) and embryo transfer (ET) are commonly known as in vitro fertilization (IVF) and embryo transfer (ET). It is a process in which the eggs and sperm are taken out separately, fertilized in culture medium, and then transferred back to the mother's uterus to develop into a fetus.

1. Umbilical cord factors. According to MHTC, umbilical cord development abnormalities, such as umbilical cord over-twisting, narrowing, twisting, true knot, single umbilical artery, etc., result in obstruction of umbilical cord blood flow; or sail placenta, cause fetal placenta circulation disorder leading to intrauterine fetal death.

试管婴儿双胎突然消失一个是怎么回事?双胎消失综合症通常发生在妊娠12周内,死亡胎囊可自溶吸收,对另一个活胎和母体没有明显不良影响.但是如果在妊娠3个月之后发生一胎死亡,胎体坏死组织发生退行性变,胎盘所释放的组织凝血活酶可通过血管到达存活胎儿导致弥漫性血栓形成,或进入母体引起血管内凝血的可能.死胎孕周越大,发病风险越高,必须严密监测母胎情况,包括凝血功能监测和胎儿宫内情况监测.

Twin disappearance syndrome usually occurs within 12 weeks of gestation. The dead foetus sac can be absorbed by autolysis and has no obvious adverse effect on the other live fetus and the mother. But if one fetus dies after 3 months of gestation, the necrotic tissue of the fetus degenerates and the tissue thromboplastin released by the placenta can reach the surviving fetus through blood vessels. Diffuse thrombosis, or the possibility of intravascular coagulation in the mother. The greater the gestational age of stillborn fetus, the higher the risk of onset. Maternal and fetal conditions must be closely monitored, including coagulation function monitoring and fetal intrauterine monitoring. http://www.sdxyer.com/
