Thickening of the placenta in pregnancy
Almost every modern woman knows,what role the placenta plays in the development of the fetus. In translation, "placenta" means "cake". It grows from the embryonic cells and develops simultaneously with the developing embryo. The placenta finishes its development and formation during pregnancy about sixteen weeks. This is because its functions are closely related to the production of pregnancy hormones.
Why do we need this "body"? Gas exchange of mother and child, the supply of nutrients to the baby's body, hormonal secretion and the function of forming immunity - all this provides the placenta. From the mother's blood, the necessary oxygen flows through the placenta to the growing fetus, and is recycled through it like carbon dioxide. All vitamins enter the growing organism in the same way, and unnecessary metabolic products are removed through it.
Not always everything goes according to the planned plan, there are alsodeviation. Changes in the structure of the placenta can have bad consequences, especially for the development of the baby. If, after an ultrasound, a pregnant woman is diagnosed with a "thickening of the placenta," this means that she has matured before the due date.
The reasons for this anomaly are differentfactors. During pregnancy, the placenta passes through four important stages, followed by an ultrasound examination. The stage of development of the placenta, when it is still homogeneous in structure, is referred to by scientific concepts as the zero degree of its maturity (up to thirty weeks). At the period from twenty-seven to thirty-four weeks of pregnancy, the stage of growth is already called the first, in it separate areas of the echogenic structure become noticeable. Multiple echogenic areas and a more undulating chorionic structure - this is already characterized by a second degree of maturity (in the interval from thirty-four to thirty-nine weeks). Aging of the placenta (the last, the third degree of maturity) can be suspected by ultrasound if its structure is lobed, and it also shows a variety of calcifications (usually from the thirty-seventh week). In another way, this stage is called calcification of the placenta.
Ultrasound allows us to determinethickness of the placenta. At a certain time, it must correspond to a specific thickness. Otherwise, this is called premature aging of the placenta, which can not fully perform its functions and provide the fetus with all the necessary substances for its normal formation. Thickening of the placenta is dangerous for the developing baby. The baby does not receive a sufficient amount of oxygen and nutrients, as a result of which various deviations from normal development begin to occur.
Placenta thickening is a serious situation whenpregnancy, it is fraught with interruption of pregnancy or fetal death. Doctors in this case carry out a complete, comprehensive examination of the child and mother, and also prescribe a special therapy, in each case that is different. More often the baby manages to save.
What causes the early aging of the placenta?
- Abortions. As a result of this procedure, the walls of the uterus become thin, their normal nutrition is disturbed. Complicated births that precede pregnancy are also a provocative factor.
- Disorders in the endocrine system.
- Chronic diseases of the kidneys, the environment-vascular system, etc.
- Thickening of the placenta may occur due to different Rh factors in the child and mother.
- Severe gestosis (toxicosis) during pregnancy.
- Placental abruption, at an early stage; its low position. It can cause a miscarriage.
- Multiple pregnancy.
