The technology of IVF has created lovely babies in infertility families, so that everyone can successfully fulfill their own hope of pregnancy. To promote pregnancy in vitro, we believe that we will encounter a variety of problems. For example, what is the sudden disappearance of twins in vitro babies? Xiaobian takes you to know about it.

                    試管嬰兒是體外受精-胚胎移植技術的俗稱,是分別將卵子和精子取出后,置于培養液內使其受精,再將胚胎移植回母體子宮內發育成胎兒的過程.

                    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.臍帶因素.根據MHTC表示臍帶發育異常,如臍帶過度扭轉、臍帶變窄、纏繞、真結、單臍動脈等,造成臍帶血管血流受阻;或者帆狀胎盤,造成胎兒胎盤循環障礙導致胎死宮內.

                    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.

                    2.胎盤因素.先兆子癇使胎盤缺血、缺氧、梗死、胎盤早剝;前置胎盤;球拍狀胎盤等.

                    2. Placental factors. Preeclampsia causes placental ischemia, hypoxia, infarction, placental abruption; placenta previa; racket placenta, etc.

                    3.胎兒畸形.雙胎畸形的發生率是單胎的兩倍,如嚴重先天性心臟病,胎兒腫瘤、神經系統畸形等.

                    3. Fetal malformations. The incidence of twin malformations is twice that of singletons, such as severe congenital heart disease, fetal neoplasms, nervous system malformations, etc.

                    試管嬰兒雙胎突然消失一個是怎么回事?雙胎消失綜合癥通常發生在妊娠12周內,死亡胎囊可自溶吸收,對另一個活胎和母體沒有明顯不良影響.但是如果在妊娠3個月之后發生一胎死亡,胎體壞死組織發生退行性變,胎盤所釋放的組織凝血活酶可通過血管到達存活胎兒導致彌漫性血栓形成,或進入母體引起血管內凝血的可能.死胎孕周越大,發病風險越高,必須嚴密監測母胎情況,包括凝血功能監測和胎兒宮內情況監測.

                    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.danihemmat.com/
