Is fetal arrest due to fetal x monomer

summary

For pregnant mothers, the health of the fetus is more important than anything, so it is very necessary to go to the obstetrics and gynecology department for regular physical examination. When the situation of the fetus is unstable, we need to find out the reasons. Let's talk about whether the fetal arrest is due to fetal monomer X.

Is fetal arrest due to fetal x monomer

First, if the embryo is stopped, the mother will have a series of changes to facilitate its excretion. The first is the decrease of estrogen and progesterone, the body produces the effect of immune rejection to the embryo, and the blood vessels between the mother and the embryo form thrombus, which may lead to vaginal bleeding in this process. At this time of bleeding performance we call threatened abortion, is the embryo to be discharged from the body signal.

Second: fetal arrest refers to the early pregnancy embryo development stopped due to some reason. B-ultrasound examination showed that the embryo bud or fetus in the gestational sac was irregular, without fetal heart beat, or the gestational sac was withered. Clinical belongs to the category of abortion or stillbirth. More than 90% of the cases are related to the abnormality of embryo itself. A few cases are related to luteal insufficiency, hyperprolactinemia, thyroid dysfunction and diabetes.

Third: if the chromosome is abnormal, it will also lead to early abortion. Chromosome abnormalities include quantitative and structural abnormalities, which can be divided into aneuploid and polyploid. The most common abnormal karyotype is aneuploid trisomy, and 16 trisomy accounts for 1 / 3, which is often fatal.

matters needing attention

There are many reasons for fetal dystocia, among which fetal x monomer may cause fetal dystocia, but not all fetal dystocia is caused by fetal X chromosome monosomy. Therefore, when fetal dystocia is found during pregnancy examination, we should seek help from a doctor in time.
