Disturbance of uterine blood flow during pregnancy: causes. treatment

One of the most powerful research during pregnancy - the analysis of arterial blood flow in the uterus, the umbilical cord woman in cerebral vessels and the aorta baby, since it is often the cause of death of the fetus and newborn, their pathology and morbidity is violation of uterine blood flow .

The placenta retains the fetus and transmits oxygen and nutrition from the mother's blood and takes out the products of the metabolism of the growing organism.

It is the placenta that is the unifying link between the maternal vascular system that connects the uterus and the placenta, and the fetus that goes into the umbilical arteries and leads to the fetus. These circulatory systems are separated by a membrane that prevents the mixing of blood between the mother and the baby. The placenta is a barrier that can withstand many harmful substances and viruses. However, there is a possibility of placental insufficiency, and many properties are under threat. This is the ability to perform metabolic, trophic, endocrine, transport, perinatal and other vital functions.

Such a state can significantly worsen and disrupt the metabolism between mother and child organisms, thus causing serious consequences.

Causes of

Among the reasons for the violation of uterine blood flow include pneumonia, increased blood pressure, intrauterine infections and oxygen deficiency in the fetus (hypoxia). To diagnose the system of blood flow, Doppler (3D ultrasound) of vessels is used.

This makes it possible to assess the malformations of the heart and diagnose retro placental bleeding by monitoring blood flow.

This is very effective and important method because it makes it possible to identify defects in the smallest blood vessels that make up the microcirculation, to control the specificity of vnutriplatsentarnoy hemodynamics and monitor the amount of nutrients and oxygen supplied to the system of the fetus. With its use, there is the possibility of early diagnosis of obstetric complications.

As you know, the early onset of correction or treatment gives a high guarantee of preventing circulatory disorders, and accordingly, the pathologies caused by them.

The degree of disturbance of uterine blood flow during pregnancy

Hemodynamic disorders during pregnancy are divided in degrees of severity.

In the first degree there are two subspecies.

  • Subspecies 1A is characterized by mild violation of uteroplacental blood flow and blood circulation is preserved here. Most often this pathology is caused by intrauterine infection;

  • With the subspecies 1B uteroplacental blood flow is preserved, but in the placental placenta appear pathologies.

  • At the second degree of disturbance, both systems of blood flow are exposed, but no radical changes occur in this case.

    At the third degree on the utero-fetal level, there are violations in the circulation of blood, caused by problems of uterine-placental blood flow.


    With timely detection and proper treatment at the first degree of fetal death, it is almost always possible to avoid. At the second degree perinatal mortality already makes 133%, and at the third reaches 467%.

    Dopplerometric studies showed ineffectiveness of treatment of placental insufficiency in women with hemodynamic pathologies of the third degree.

    Here, perinatal mortality in normal births has reached 50%, but caesarean section helps to avoid losses. 35.5% of newborns with the first degree, 45.5% from the second degree, and 88.2% from the third are subjected to intensive therapy.

    Pregnant women should remember that the mother's condition is transmitted completely and, in order to avoid complications, she should prescribe her diet from food, which contains a large number of micro- and macronutrients, vitamins, the necessary amount of proteins, carbohydrates and fats. In the absence of edema, the amount of fluid consumed should not be less than a liter-one and a half. It is necessary to track changes in body weight, and by the end of pregnancy, the weight gain should not be more than ten kilograms. There are risk groups that need drug prevention, which favors the adequate interaction of mother and fetal systems, preventing the violation of uteroplacental blood circulation.
