Violation of blood flow 1 A degree in pregnancy: possible causes, symptoms, diagnosis and treatment

During pregnancy, the female body begins to rebuild. Therefore, during this period it is so important to keep under control the condition of both women and fetuses. As shown by medical statistics, a fairly large number of pregnant women observed a violation of blood flow. The additional circle of blood circulation that has arisen in the body requires constant monitoring by specialists. His violation can lead to the death of the fetus, and this can happen at any time of pregnancy. Let's try to understand why the blood flow during pregnancy is disturbed.

A bit of theory

Everyone knows that the placenta acts as a link between the body of a woman and the fetus. In this complex system, there are two types of blood circulation - placental and fetal. Any violation of one of them can lead to quite sad consequences, including the development of a variety of diseases. The severity of the problem is assessed only by a doctor.

In this case, a woman who is at the 30th week of pregnancy should definitely undergo a special ultrasound diagnosis, which clearly shows the vessels of the placenta in a three-dimensional image. If there is any violation, the doctor will necessarily see it, as there is a change in the spatial ratio of uterine and fetoplacental blood circulation. This is a very dangerous state of the body, as the respiratory function is depressed, and the development of the fetus is suspended.

Degrees of violation

Medicine identifies three degrees of severity of this pathology. The easiest is the first degree, when insufficient blood circulation has not yet reached its critical values. In this case, the hemodynamics of the fetus is in a satisfactory state. There is a violation of uteroplacental blood flow of 1 A degree and insufficient placental-placental blood circulation of 1 B degree.

The second degree is characterized by a deterioration in the blood supply to the fetus. In 50% of cases, there is a decrease in the maximum rate of blood flow through all the valves of the heart, and this violation is observed in the fetus and in the uterine arteries.

Quite often in a short period of time, the second degree goes to the third. In this case, the blood flow practically ceases to flow to the fetus, which can cause its hypoxia. There is a great chance of reducing diastolic blood flow in the aorta, and in some cases it may completely disappear.

Causes

If there was a violation of blood flow of 1 degree during pregnancy, the reasons leading to this may be different. Numerous adverse factors can affect the placenta not only during its formation, but also at later times. Medical practice identifies primary and secondary circulatory insufficiency, which is why the functioning of the placenta is disrupted, which acts as a transport, protective, immune, metabolic and endocrine organ.

Thus, a violation of 1 A blood flow during pregnancy can occur for the following reasons:

• Uterine tumor;
• Genetic defects;
• Consequences of abortion;
• infectious diseases;
• hypertonic disease;
• Adrenal and thyroid gland diseases;
• Structural anomalies;
• Hormonal dysfunction;
• Late toxicosis ;
• Thromboses, atherosclerosis;
• diabetes.

If this pathology is not corrected in time, then after 6 weeks, a slight violation of the blood flow can go to the third stage. If a problem is detected at the 30th week, the doctor still has enough time to take appropriate measures to restore normal blood circulation.

Symptoms

Any pathology is characterized by its clinical picture, so the doctor can make an appropriate conclusion. The lack of hemodynamics leads to a change in the functioning of the placenta, which causes the fetus to suffer. To him in a limited number begin to receive the necessary nutrients and oxygen, and there is a slowdown in the excretion of metabolic products. The signs of fetal hypoxia begin to appear , as a result of which the intrauterine development of the fetus is suspended.

Thus, if there is a violation of blood flow during pregnancy, the symptoms of this condition manifest themselves as follows:

• cardiopalmus;
• Decrease or increase in motor activity of the fetus;
• Incompatibility of the volume of the stomach to a specific period of pregnancy.

Such signs usually arise when the placental insufficiency is decompensated . If a violation of uterine blood flow during pregnancy 1 A or 1 B degree, these symptoms are not yet evident, as hemodynamics is compensated. It is usually found in diagnostic studies.

Diagnostics

To detect a violation of 1 A blood flow during pregnancy, it is necessary to undergo a series of examinations, with which help determine the type and extent of the changes that have arisen, and also determine the condition of the fetus. In this case, the doctor prescribes the following procedures:

• A blood test for hormones such as estrogens, chorionic gonadotropin, progesterone;
• Cardiotocography;
• ultrasonography;
• Doppler.

In some cases, the doctor already at the time of the examination is able to determine the violation, based on the child's heart rate, which is calculated during auscultation. But the most reliable results are usually obtained after laboratory and instrumental research.

Treatment

Disrupted uteroplacental blood flow of any degree must be treated. In general, treatment activities are aimed at preventing pathology from further progressing. Hemodynamics is normalized only if there is a violation of blood flow 1 B degree.

In pregnancy, flowing with abnormalities, various means are used to improve the condition of the fetus. Basically, conservative methods of treatment are used. Surgical intervention is possible only in case of complications and for vital indications. With the normalization of blood flow disorders, a set of measures is used - pathogenetic, etiotropic and symptomatic treatment.

Medication

Most often, the violation of blood flow 1 A degree during pregnancy is corrected with the help of medications. When identifying the initial signs of a violation, treatment is done on an outpatient basis. More severe circulatory failure requires hospitalization in the hospital.

The following preparations are used for treatment:

• Antispasmodics - "Eufillin", "No-shpa";
• Cardiovascular - "Actovegin";
• Antiagreganty - "Kurantil";
• Vitamins and trace elements - "Ascorbic acid", "Magne B6";
• Hepatoprotectors - "Hofitol", "Essentiale";
• Tocoliths - "Partusisten", "Ginipral";
• Improving microcirculation of blood - "Trental";
• Antihypoxants - "Instenon";
• Metabolic - "ATP".

Usually to improve the condition, two courses of therapy are performed - immediately after the diagnosis was made and at the time of 32-34 weeks. After this, the doctor decides on the method of delivery. This is especially important if the circulatory disturbance is severe. If the blood flow of 1 degree is violated, the birth is natural.

Surgery

If the violation of the blood flow is clearly pronounced, an emergency delivery is carried out. In case of ineffectiveness of conservative treatment, even in case of easy violation the decision is made within two days. Cesarean section is usually performed. If it is planned at a gestation less than 32 weeks, then assess the condition of the fetus and its viability.

Preventive measures

To avoid such a pathological condition, as a violation of blood flow 1 A degree during pregnancy, preventive measures should be taken. A woman who expects a child should consume foods containing the necessary vitamins, micro- and macronutrients, fats, carbohydrates and proteins. Every day, you should consume at least 1.5 liters of fluid, but only if you do not suffer from swelling.

It is also important to keep your weight under control. During pregnancy, the recommended weight gain should not exceed 10 kg. Women at risk are prevented with drugs to interact with the mother and fetus system and prevent the extremely dangerous dysfunction of uteroplacental blood circulation. An important role is played also by the timely corrected method of conducting labor. But it should be remembered that even compliance with these measures does not exclude the occurrence of severe neurological complications.

Conclusion

Thus, it is important to control blood flow during pregnancy. The causes of circulatory disorders may be different. The main thing is to monitor your health, and timely detection of pathology will help prevent severe consequences for the future child.
