embryo stops developing
Introduction
Introduction Fetal stoppage refers to the developmental stop of an embryo in early pregnancy due to some reason. B-ultrasound examination showed fetal buds in the gestational sac or fetal form irregularities, no fetal heartbeat, or manifested as gestational sac. Clinically, it belongs to the category of abortion or stillbirth. It used to be called expired abortion or missed abortion. There are many reasons for the embryo to stop developing.
Cause
Cause
Fetal stoppage refers to the developmental stop of an embryo in early pregnancy due to some reason. There are many reasons for the development of the fetus, embryonic hypoplasia, abnormal pregnancy, placental dysplasia, maternal and child blood group incompatibility; female endocrine dysfunction, genital diseases; female systemic disease during pregnancy; female trauma during pregnancy, sudden changes in emotion; male sperm Quality problems, such as dysplasia, deformity, etc.; and chromosomal abnormalities in both men and women.

When the embryo stops developing, it doesn't feel like a pregnant mom. If it takes a long time, there will be symptoms of bleeding. If you still have menstruation during pregnancy, then it must be that the embryo must stop developing. Signs of embryonic development: The fetus eight weeks before pregnancy is medically called an embryo. Embryo cessation of development refers to the early development of embryos for some reason, which is a form of spontaneous abortion. B-ultrasound examination showed fetal buds in the gestational sac or fetal form irregularities, no fetal heartbeat, or empty capsules.
1. The disappearance of yolk sac is generally indicated in the 7th-9th gestational week. If the yolk sac is still not found after repeated searching, it may be the destruction of the egg or the indication of fetal malformation.
2, pregnancy sac is less than gestation
Need to pay attention to accurately calculate the gestational age, we must pay attention to observe the size, shape, wall changes of the gestational sac, the presence or absence of yolk sac, fetal bud and fetal heart beat in the capsule to indicate signs of embryo survival. Can not be diagnosed by the gestational sac just less than the gestational age.
3. Embryo death type
For the irregular menstrual cycle, the last menstrual period is not pleased and the first B ultrasound is difficult to determine the diagnosis, can be reviewed after 1-2 weeks, such as yolk sac, fetal bud and fetal heart beat still can not see, shrinking or collapse The gestational sac moves down the cervix, which is the basis for fetal death. In general, when the pregnant mother is diagnosed as having stopped embryonic development, she needs to undergo a miscarriage treatment under the guidance of a doctor. Fetal stop-up is different from early pregnancy. There is a big risk in using the drug flow method. At this time, the embryo has formed and adhered to the uterine wall, and it is not easy to completely drain. If it remains in the uterus for a long time, it will cause intrauterine infection and damage the uterus. The endometrium, which in turn causes occlusion of the fallopian tube, leads to infertility. Therefore, after the child is stopped, the doctor will generally recommend hospitalization for curettage. Because fetal arrest is likely to cause major bleeding after surgery, it must be hospitalized for a period of time.
Diagnosis
Differential diagnosis
Need to identify with the slow development of embryonic development.
Slow embryonic development: Intrauterine growth retardation refers to two standard deviations of fetal weight below the normal average body weight during pregnancy. Generally divided into three categories: endogenous symmetry fetal intrauterine growth retardation, external cause of heterogeneous fetal intrauterine growth retardation, external factor symmetry fetal intrauterine growth retardation.
When the embryo stops developing, it doesn't feel like a pregnant mom. If it takes a long time, there will be symptoms of bleeding. If you still have menstruation during pregnancy, then it must be that the embryo must stop developing.
