Sometimes women who are in a position after hearing the term "placental infarction" are interested in the doctor what it is. This kind of condition of the child's place is caused by a violation of the normal blood flow of the placenta. It consists in the withering away of the site of its tissue.
What are the different types of placenta infarction?
Depending on what caused the infarction of the placenta, the following types are distinguished:
- calcareous form.
The first type develops in the event that there is a bleeding from a vessel localized in the dyscedula. Subsequently, after a while it goes into the second form.
White infarction is the result of excessive deposition of fibrin, which gives this color.
Lime form of a placental infarct is rare. It is caused by the precipitation of calcium molecules on the walls of damaged blood vessels.
Because of what is developing a placenta infarction?
The causes of myocardial infarction are quite numerous. Therefore, it is often difficult to determine exactly the one that led to the disease in a single case. Aggravating factors that often lead to the development of such a disease are:
- prolonged toxicosis;
- a change in the weight of the pregnant woman to a greater or lesser extent;
- increased blood pressure;
- disruption of the excretory system (kidney disease).
To determine the exact cause that led to the development of a placenta infarction, a thorough examination is carried out, including: ultrasound, laboratory tests. Sometimes the difficulty in diagnosis lies in the fact that the placenta itself is located on the back of the uterus, and its careful examination of the fetus. In such a situation, doctors will learn about the violation of the normal state of a child's place by changing the baby's heartbeat, a similar disease leads to oxygen starvation of the fetus, as indicated by the rapid heart rate.
How is the placenta infarction determined?
Symptoms of such a violation, as a placenta infarction, are few. That is why this kind of condition is diagnosed with a planned ultrasound. However, usually, the presence of a violation in a pregnant woman says:
- frequent, excessive fetal movements;
- increased heart rate in the fetus;
- the appearance of bloody discharge (if a heart attack is accompanied by a detachment of the placenta).
The very same pregnant woman, with the defeat of a small part of the placenta, feels as usual. This fact sometimes makes it difficult to diagnose early the violation of placental blood flow. Most often it is found on CTG, in which the fetal heart rate is counted and its activity is analyzed. The results obtained from this study are confirmed by ultrasound.
What can placental infarction lead to?
The most pregnant woman who has learned about the presence of such a disorder is interested in what the consequences of a placental infarction are, and whether her necrosis can come.
The risk of complications in this case depends on how the placenta is located in the uterus and what its dimensions are. Most often, a single heart attack, having a small size, does not represent a danger. However, the presence of 3 or more such sites, or 1, 3 cm in size, can lead to fetoplacental insufficiency. Such a violation in the late term leads to the development of fetal hypoxia, which negatively affects its intrauterine development. In those cases where the lesion reaches 1/3 of the entire placenta size, the fetal death occurs.
Thus, in order to timely establish a violation is necessary to conduct ultrasound. In those cases when a placenta infarct is diagnosed, the pregnant woman is under observation throughout the term.
