What is the cause of placental hematoma?

When the baby is in the mother's belly, it mainly exists inside the uterus, and there is an organ attached to the outside of the uterus, which is the placenta. The placenta is an important material organ that connects the baby with the mother's maternal nutrition. In the eyes of many women, the placenta in the mother's body has a good effect on beauty and skin care, so many women like to eat the placenta. But when the placenta was in the mother's belly, there was a hematoma problem. What caused it?

The placental hematoma you mentioned may be related to maternal and fetal blood circulation disorders, or the influence of the placenta's own circulation disorders, or it may be directly related to the subamniotic hematoma caused by fetal circulation disorders. The above situation will not affect the next pregnancy. Please note that as long as the placenta is completely detached after premature birth, you can rest assured. What is the placenta? The placenta is an organ for material exchange between the mother and the fetus. It is a combination of embryonic and maternal tissues and the source of life for the baby. It attaches to the uterus and receives nutrients and oxygen for the baby inside. If it becomes abnormal or aged, it will directly affect the baby's growth and development, and even endanger the baby's life.

The "Chinese Pharmacopoeia" points out that the traditional Chinese medicine "placenta" made by removing the amniotic membrane and umbilical cord from a fresh placenta of a healthy person, repeatedly flushing to remove the blood, steaming or boiling in boiling water and then drying does have a certain effect of warming the kidney and replenishing essence, invigorating qi and nourishing blood, but it is not a "tonic" as some people boast, and it can easily harm the body if taken improperly. From the perspective of modern medicine, the composition of the placenta is relatively complex, and its active ingredients are mostly protein substances. They must be prepared into injections and injected intramuscularly to be effective. Oral administration is ineffective.

How is the placenta formed?

The placenta is composed of the amnion, the chorionic villi (also known as the dense chorionic villi) and the decidua basalis.

1. The amnion constitutes the fetal part of the placenta and is the innermost layer of the placenta. The amniotic membrane is smooth, has no blood vessels, nerves or lymph, and has a certain degree of elasticity.

2. The chorionic villi constitute the fetal part of the placenta and are the main part of the placenta.

The villi in contact with the basal decidua are called chorionic villi because they are rich in nutrition and well developed. The ends of the villi suspended in the intervillous space filled with maternal blood are called free villi, and those that grow into the basal decidua are called fixed villi. The placental septum that grows from the decidual plate incompletely separates the fetal lobe into maternal lobes. Each maternal lobe contains several fetal lobes, and each maternal lobe has its own spiral artery to supply blood.

The spiral arteries of the pregnant woman's uterus (also called the uteroplacental arteries) pass through the decidual plate into the maternal lobe. The material exchange between mother and fetus takes place in the villi of the fetal lobule. This means that the fetal blood goes through the umbilical artery to the villus capillaries, and exchanges materials with the maternal blood in the intervillous space. The two are not directly connected. Chorionic tissue structure: The villous trophoblast of full-term placenta is mainly composed of syncytiotrophoblasts, and cytotrophoblasts are only scattered. The inner layer of the trophoblast is the basement membrane, which has the function of placental barrier.

3. The decidua basalis constitutes the maternal part of the placenta. The surface of the basal decidua is covered with a layer of trophoblast cells from the fixed villi, which together with the basal decidua form the bottom of the intervillous space, called the decidual plate. From this plate, some decidual septa extend toward the chorion, dividing the maternal surface of the placenta into about 20 maternal lobes visible to the naked eye.
