Will the umbilical cord change at the edge of the placenta?

Many unexpected problems can occur during pregnancy. The fetus continues to grow over time, and some problems may be discovered after delivery. For example, the problem with the umbilical cord. Normally, there should be no problem with the umbilical cord being next to the fetus. But some fetuses may be different, so the concern is the changes in the umbilical cord. Will the umbilical cord change at the edge of the placenta?

Is it serious if the umbilical cord is at the edge of the placenta?

As long as it does not affect children's absorption, it is not a big problem.

During pregnancy, the placenta is relatively thick. In this case, you should look at the coverage area of ​​the placenta and whether there is any discomfort behind the placenta. If so, you may consider placental abruption. If there is no problem, simply having a thick placenta will not have any adverse effects. In addition, a part of the placenta may be relatively thick but cover a small area. So there is no need to worry about this situation.

The placenta is a transitional organ formed by the union of the embryonic membrane and the maternal endometrium during pregnancy in metatherian and eutherian mammals for the exchange of substances between mother and child. The fetus develops in the uterus and relies on the placenta to obtain nutrition from the mother, while both maintain a considerable degree of independence. The placenta also produces a variety of hormones that maintain pregnancy and is an important endocrine organ. Some reptiles and fish also reproduce by giving birth to their offspring live. The embryo grows some auxiliary structures such as yolk sac and gill filaments that are closely integrated with the maternal tissues to achieve the exchange of substances between mother and child. This structure is called a pseudoplacenta. The placenta after childbirth is also a traditional Chinese medicine, called human placenta and placenta.

The placenta is an organ for the exchange of substances between the mother and the fetus. It is a combination of embryonic and maternal tissues and is composed of the amniotic membrane, chorion frondosum and decidua basalis. The placenta is also called afterbirth, chorion, placenta, afterbirth, and fetal membrane.

What are abnormal placentas?

1. Placenta previa: Under normal circumstances, the placenta should be attached to the posterior wall, anterior wall or side wall of the uterus. But in some cases, the placenta is attached to the top of the internal cervix like a small hat, just sitting on the head or buttocks of the fetus. This situation is called placenta previa. According to the location of the placenta previa, it can be divided into complete (or central) placenta previa; partial placenta previa; marginal (or low-lying) placenta previa.

2. Placental abruption: When a normally positioned placenta partially or completely separates from the uterine wall before the fetus is delivered, it is called placental abruption. Placental abruption and placenta previa are both major causes of bleeding in late pregnancy.

Once a dangerous situation occurs, in principle, the fetus should be delivered as soon as possible. Only after the fetus is delivered and the placenta is expelled, the bleeding of the pregnant woman can be controlled and the uterus can quickly contract to stop the bleeding.

3. Adhesion placenta: Sometimes, after the fetus is born successfully, the placenta cannot be delivered for a long time. This is often caused by inflammatory changes in the decidua or excessive growth of the villi, which leads to abnormal placental implantation. If the villi penetrate deep into the basal layer of the decidua, the placenta adheres to the uterine wall, which is called accreta placenta.

4. Placenta accreta: If the villi penetrate deeper into the myometrium, causing the placenta and uterine wall to adhere together, it is called placenta accreta. Whether it is placenta accreta or placenta accreta, it can make placental separation difficult during delivery and cause heavy bleeding. For an adherent placenta, the midwife needs to enter the uterine cavity by hand to remove it; for an accreta placenta, it cannot be removed by hand. If it is removed forcibly, bleeding and shock will occur, and the uterine muscles will be ruptured, causing uterine perforation and infection, with serious consequences. At this time, a cesarean section should be performed immediately to alleviate the crisis.
