What does the second level of the posterior wall of the uterus mean? The anatomy of female uterine cavity is divided into anterior wall, posterior wall, bottom and lower segment. Posterior placental wall indicates that the placenta is attached to the posterior uterine wall. Stay away from the lower end of the uterus. The most dangerous position of placenta is below the lower segment. There are complete and partial placenta previa. Placenta is attached to the front or back wall of the uterus, or to the left and right sides, facing south, north, east and west like a window of a room, and has nothing to do with childbirth. Therefore, the anterior and posterior walls of the placenta are a normal attachment, but there is no big difference. Related to childbirth is the placenta. If it is attached near the uterine orifice, the so-called placenta previa means that the placenta is in front of the fetus, which affects the birth canal and will affect our delivery. The pregnancy test showed that the placenta was attached to the posterior wall of uterus. So don't worry, it won't have any effect on the baby.
We know that the posterior wall of placenta refers to the position of placenta, which is located in the anterior wall, posterior wall, left wall and right wall of uterus. These are very normal postures, which are also conducive to the growth and development of the fetus. Grade 2, this is the classification of placental maturity. Generally speaking, placentas are classified into 0 grade,/kloc-0 grade, 2 grade and 3 grade according to maturity. The third-grade placenta is aging, which will affect the absorption of nutrients by the fetus. The second level of placenta means that the placenta is mature and the fetus is mature. Therefore, the second grade of placenta posterior wall means that the placenta is in the posterior wall of uterus, the maturity is grade 2, and the fetus is about to be born.
The fetus is mature and can be delivered at this time. Expectant mothers should make corresponding psychological preparations to welcome the birth of the baby. However, it is also necessary to consider the time of pregnancy. If it is normal after 36 weeks of pregnancy, expectant mothers need to observe the development of the next placenta. Also note that the more mature the placenta, the better.
How long is placental maturity level 2? According to B-ultrasound imaging, there are zero, one, two and three levels. Secondary placenta generally refers to placental maturity, and secondary placenta generally appears after term. However, if there is preeclampsia or placental growth restriction, some pregnant women may have small blood clots in the placenta. In this case, her placental maturity level may soon appear three levels. For the second kind of pregnant women, it is necessary to monitor the fetal growth, amniotic fluid and fetal heart rate regularly, and pregnant mothers should count their fetal movements every day for comprehensive screening. However, as for the second level of placental maturity, it can only show that the placenta is mature, because the delivery mechanism is complex, and it is unscientific not to assume that it will be born after three or four weeks just because of the second level of placenta. However, if the placenta is secondary, it means that the placenta is mature and the survival rate of the fetus is high.
Placental maturity level 2 generally appears after 36 weeks of pregnancy, and can be diagnosed in time through B-ultrasound images. The standard is that the fluff board is notched. If it extends to the placental parenchyma but does not reach the basal layer, the placental parenchyma particles thicken and appear strong short columnar echo, and at the same time, the basal layer may appear irregular strong strip echo, parallel to the muscle wall.
Everyone's placental maturity is different: second trimester (12-28 weeks)-placental grade 0; Late pregnancy (30-32 weeks)-placenta 1 grade; After 36 weeks-Placenta grade 2 (more mature). If the placenta grade 3 is found before 37 weeks, combined with the biparietal diameter and the estimated fetal weight of 2500 grams, the premature placenta should be considered and the possibility of intrauterine growth retardation should be guarded. At 38 weeks, the placenta entered grade 3, which marked the maturity of the placenta.
