Violation of blood flow during pregnancy can lead to irreversible consequences for the child. Retardation of intrauterine development, hypoxia, vices incompatible with life and even fetal death - this is an approximate list of complications that may arise from a malfunction in the well-functioning system of mother-placenta-child. Therefore, knowing what causes the violation of blood flow during pregnancy, doctors closely monitor the condition of the placenta and try to take into account all possible risk factors at the beginning of pregnancy.
Causes of blood flow disorders during pregnancy
Everyone knows that the placenta is a special temporary organ that unites the two circulatory systems: the fetus and the mother. The immediate purpose of the placenta is the provision of nutrients and the protection of crumbs. In addition, the body displays the products of the vital activity of a small organism. The placenta interacts with the vascular system of the mother and her baby, hence the two types of blood flow: utero-placental and fetal placental. If one of them is violated, the entire system suffers, and, as a consequence, the baby.
There are several reasons for this pathological condition. According to scientists, an important role in the formation of a normal placenta, plays a genetic set. However, other factors also affect this process. In particular, the risk group includes women who:
- began to live early sex life;
- had several sexual partners;
- took drugs, abused alcohol and smoked;
- have chronic diseases;
- have a history of spontaneous miscarriages , frozen pregnancies and abortions .
Types of hemodynamic disorders
There are several types of placental insufficiency, each of which has its own peculiarities and risks:
- Disturbance of blood flow during pregnancy 1a degree - this condition is characterized by the presence of abnormalities in utero-placental blood flow, while in the placenta-fetus subsystem, pathologies are not observed. In pregnancy, impaired blood flow 1a degree is not a critical condition and is easily treatable.
- Infringement of a blood flow at pregnancy 1b degree - in this case a pathology is observed in a fruit-placental blood flow. However, the state of the child is still satisfactory.
- Infringement of a blood flow at pregnancy of 2 and 3 degrees - more serious deviations in work of both systems, leading to complications, up to death of a fruit.
In order to avoid irreversible consequences and the death of a child, the violation of blood flow during pregnancy should be detected in a timely manner. For this, future mothers are doing ultrasound with dopplerometry. To date, this is the only, but very effective method of diagnosis.
