The placenta is an important fetal appendage during pregnancy, serving as a crucial site for oxygen and nutrient exchange between the mother and fetus. The normal position of the placenta is usually located on the anterior wall, posterior wall, bilateral walls, or uterine floor of the uterine body. So what does the posterior wall of the placenta mean?
The posterior wall of the placenta refers to the attachment of the placenta to the posterior wall of the uterus, which is a normal position of the placenta and does not affect the delivery of the fetus or the progression of the pregnancy. As long as the placental position is not low, no matter where it is attached, it will not have any impact on pregnancy. So pregnant women don't have to worry too much, the posterior wall of the placenta is very normal. The placenta, whether located on the anterior or posterior wall of the uterus, has little impact on the fetus as long as it is not placenta previa or placenta previa.
If the lower edge of the placenta completely covers the cervix, it belongs to the central type of placenta previa. The placenta in this position is quite dangerous. If this type of placenta is found during pregnancy, attention must be paid to vaginal bleeding, and sexual intercourse is prohibited throughout the entire pregnancy. If the placenta is still in this condition during the due date, it is recommended that pregnant women choose cesarean section surgery.
The advantage of the posterior wall of the placenta is that even if there is a displacement of the placenta, it is not easy to cut the placenta during cesarean section surgery. The choice of uterine incision for cesarean section surgery is usually in the lower segment of the anterior wall of the uterus. If the placenta is located in the lower segment of the anterior wall of the uterus, there may be significant bleeding when the incision touches the placenta, which can be avoided by the posterior wall.
