Whether uzi to show the frozen pregnancy. Frozen pregnancy on ultrasound: how is it determined what it looks like? Non-developing pregnancy in late gestation

I have already written my story, but I will write it again. I didn’t have ST and I wasn’t given such diagnoses, but it was different.
At 6 weeks, I started to have a spotting, the doctor advised me to go to the hospital, but since I have an older child, I couldn’t do this, then they prescribed me medication and told me about bed rest. I lay down for 6 days almost without getting up and taking medication, and everything went away for me. I'm very. rejoiced at this and the next. After a day of resting all the places for myself, I started cooking in the kitchen. To celebrate, I made so many dishes that I don’t even remember everything =)) But I spent almost half a day in the kitchen on my feet. The evening ended happily, we ate and went to bed. At night, when my daughter woke up and asked to go to the toilet, I got up and my legs began to flow heavily. I was frightened and ran to the bath, I began to bleed heavily. I called an ambulance and packed my bags. The doctor came and looked at him and said that he needed to be hospitalized urgently. While we were driving in the car, she reassured me and said that I had many chances that everything would be fine. When I was brought to the hospital it was 6 in the morning, a kind old woman received me and called the doctor. We waited for the doctor for over 30 minutes!!! Even the doctor from the ambulance began to swear. After 40 minutes, the doctor came, a terrible bitch on her face. She let the doctor out of the ambulance and started yelling at me!!! "Why haven't you undressed yet?" "Why are you sitting?" The old woman who received me stood up for me saying that she had to sit naked for 40 minutes? (it was January in the yard) I quickly undressed, then there was a command "go to the toilet" I refused, she yells again. I went to the toilet, stood there like a fool and said that everything (actually nothing happened) =)) She put me on a chair and began to examine me very painfully, climbed with her hands a hundred times. After that, there was a verdict "very heavy bleeding and urgently for reading right now" I have a very long-awaited pregnancy and I was so upset that I started yelling at the whole hospital, the doctor got scared of me))) I started screaming that I would not go anywhere without an ultrasound, and that in general, I don’t want to talk to you anymore, you are a filthy doctor and you need to kill such people))) She left and they took me to the floor. They said to wait 9 am and on the ultrasound. I cried and waited for the uzist. At 9 am I had an ultrasound. They said that the fetus corresponds to the terms, the heart is audible and that there is detachment, but not such detachments were preserved. I spent 10 days in the hospital and on the 4th day everything stopped and the spotting and bleeding stopped. I was discharged at 8 weeks. Now we are already 40 weeks without two days, I am waiting for the appearance of my daughter) We went to ultrasound with my husband, everything is fine with us, we are very hairy, etc. There were some thoughts to give birth to a daughter and bring that bitch to the doctor to show who she almost killed because she was not allowed to sleep. Later it turned out that she indiscriminately sends everyone for cleaning and that many agree because they don’t know how to behave in this situation = (It’s a pity that not everyone fights to the last for their masks (
Sorry it's so long.

Many women believe to the last: a frozen pregnancy is an ultrasound error. The birth of a strong baby is the dream of every woman. Unfortunately, often a long-awaited pregnancy proceeds with various deviations. The fading of pregnancy is a sentence for the unborn child and it is impossible to come to terms with this. Can a modern diagnostic method fail? The answers to this and some other questions can be found in the article.

Frozen or non-developing pregnancy is an interconnected combination of intrauterine death of the fetus (embryo) with absolute lethargy of the uterus muscles and impaired homeostasis response.

A normal protective reaction of the body in the event of the death of an embryo or fetus is a miscarriage - a spontaneous contraction of the muscles of the uterus, rejecting a non-viable fetus from its cavity. In the case of a frozen pregnancy, such a reaction does not occur. The difference between this type of gestation and miscarriage is the cessation of the production of the hormone progesterone, which leads to insufficient blood circulation in the uteroplacental tissues. Another medical name for a missed pregnancy is a failed miscarriage.

It is difficult to establish the only cause of the appearance of this pathology.

In 70% of the total number of cases, the reason is a genetic failure, which is often fixed in the early stages of gestation - up to 8 weeks.

The likelihood of freezing of the embryo or fetus increases in the presence of the following factors:

1. Psycho-emotional stress.
2. Physical overload.
3. Mismatch between mother and fetus in blood type and Rh factor.
4. Intoxication with harmful substances. Before and after conception, you should stop smoking, drinking alcohol and narcotic products.
5. Infectious diseases, especially untreated. The risk of complications exists throughout the entire period. A common cold knocks down the normal rhythm of the most important organs of a woman, after which deviations in the development of the fetus and its death occur.
6. Hormonal disbalance. The lack of certain hormones does not allow the embryo to firmly establish itself in the uterus. An excess of testosterone, a male hormone, affects the viability of the embryo during the first 12 weeks.
7. Pregnancy after 40 years. Age is critical for normal bearing, the condition is aggravated by the presence of chronic diseases.

Such a pathology can appear at any time. Often observed during artificial insemination of the egg. Getting pregnant in this way is not always possible on the first try.

The presence of previous miscarriages indicates reproductive problems, which increases the possibility of an abnormality.

Classification of pathology

In professional medicine, there are two types of missed pregnancy at the earliest stages, which can only be diagnosed by ultrasound:

1. Anembryony. Subdivided into types I and II. In variant 1, lags in the size of the uterus and fetal egg are found, relative to normal for a specific period. In variant 2, these indicators correspond to the norm, but there is no embryo (residual elements are visualized in the photo).
2. The death of the embryo is established in the absence of a heartbeat and signs of motor activity inherent in the normally progressing course of the process.

Type II anembryony of one ovum at the conception of twins is a special case, defined as failed twins. The remaining live embryo retains the possibility of further full development.

Symptoms of this pathology depend on the duration of pregnancy. Most often, fetal fading occurs in the early stages of gestation, during this period a woman should especially carefully monitor her condition.

You can independently understand negative changes if you suddenly:

• toxicosis disappears;
• the mammary glands are reduced.

Sometimes the signs of a frozen pregnancy in the first weeks of pregnancy are so weak that it is almost impossible to catch them on your own. A woman, on the contrary, can feel a surge of strength, pain and discomfort typical of pregnancy disappear.

Obvious signs appear already at the stage of decomposition. Not earlier than 14 days after the death of the fetus (there are cases when after 6 weeks). Constant pain in the lower abdomen begins to disturb, spotting appears, which shows a neglected form of intoxication.

At a later date, you should be wary if no fetal movement is noticed for more than 2 days. It becomes more alarming from a feeling of heaviness in the stomach, severe weakness. For a period of more than 25 weeks, abundant colostrum production may begin, which is uncharacteristic of a normal pregnancy.

It is important to establish the pathology as early as possible. This helps prevent the spread of infections and complications in the mother's body.

DIC syndrome is very dangerous, in which the blood loses its ability to clot. Abundant blood loss after the removal of a non-viable fetus or embryo can lead to a fatal result.

Prevention

In a woman's body, powerful hormonal changes occur, a lot of effort goes into the development and protection of the fetus. The immune forces of the body are falling, which must be supported by immunomodulators.

Some attention should be paid to the state of the vaginal microflora, restoring it to normal levels using available methods.

The well-known pregnancy tests for the level of hCG in the urine can provide additional information at home, if the embryo is suspected to be non-viable.

In this case, the content of the hormone in the urine gradually decreases. A few days after the death of the embryo, the morning hCG test will show one strip - a result showing the absence or fading of pregnancy.

It should be noted that experts do not recognize the hCG test for diagnosing this pathology as reliable and reliable.

ultrasound

Examination using ultrasonic waves is the most informative and affordable diagnostic method. During the entire period of gestation, for a complete picture of pregnancy, it is necessary to undergo from 2 to 4 diagnostics. Various deviations in the bearing of the fetus are an indicator for additional research.

Ultrasound in early pregnancy (ARS), after several weeks of missed periods, helps to clarify the situation on many issues:

• confirm normal uterine pregnancy;
• exclude the presence of a dangerous disease - a blistering skid, the symptoms of which and the results of laboratory tests are similar to those during pregnancy;
• set an exact date
• the quality of physiological processes characteristic of this position;
• prove the presence or absence of pregnancy with a delay in menstruation (relevant for women suffering from infertility or after artificial insemination);
• detection of various gynecological diseases: the presence of fibroids, the possible irregular structure of the uterus (saddle-shaped, doubled).

It is possible to assume anomalies in the development of an ultrasound scan of the BRS, if the heartbeat is not heard, due to the small size of the fetal egg and uterus for this period.

Ultrasound allows you to determine their specific indicators, approximately equal in the early stages for everyone, when there are still no distinctive individual characteristics.

Ultrasound is recognized as the most voluminous and accurate diagnostic method.

Most often, an ultrasound scan erroneously diagnoses a missed pregnancy at an early stage of 6-7 weeks:

1. A fixed approximate date of conception leads to an incorrect result. During this period, the heartbeat of the embryo should be heard, a discrepancy of 1-2 days matters. The absence of a heartbeat gives reason to consider the embryo not alive. An experienced doctor, not excluding the possibility of an error, conducts a second examination in a week, which confirms or refutes the diagnosis.
2. The peculiarity of the course of ectopic development of the embryo makes it difficult to diagnose. The so-called false fetal egg without an embryo, filled with liquid, can be fixed in the uterus. Pathological development takes place in the fallopian tube. A medical error like this can cost a woman her life. Only transvaginal ultrasound can absolutely correctly establish an abnormal ectopic pregnancy.
3. In practice, cases are known when, during laboratory tests that disprove pregnancy, an ultrasound scan inside the uterus reveals a specific body with smooth contours, similar to an embryo. In the uterine cavity, there may be a glandular polyp, a myomatous nodule, or a cystic cyst, which are mistaken for a fetal egg.

As practice shows, the probability of developing a pathology exists for 28 obstetric weeks of bearing a child. The last weeks of the term are no exception.

Transvaginal ultrasound of a frozen pregnancy in the early stages is recognized as more informative than a study through a massive abdominal wall. Up to 12 obstetric weeks (from the first day of the last menstruation), it is absolutely safe and is recommended for detecting an ectopic pregnancy. 6 weeks after conception, the transvaginal method shows the heartbeat of the embryo, and after seven, it allows you to see the presence of him in the gestational sac.

Fading of the fetus (its death) is possible until the 20th week of pregnancy. What is the essence of a missed pregnancy? The answer is simple: "For various reasons, intrauterine death of the embryo occurs." Usually, a frozen pregnancy becomes a prerequisite for a miscarriage. The dead fetus is rejected by the body (but this is not in all cases).

When making this diagnosis, specialists should conduct repeated diagnostics. Initially, when symptoms of this pathology appear, doctors refer the pregnant woman for additional ultrasound examination.

Every woman in a position hopes that the diagnosis of a frozen pregnancy is an ultrasound error and no more. Naturally, expectant mothers are concerned about the accuracy of ultrasound and the possibility of making mistakes in ultrasound. Can ultrasound make a mistake in determining the fading of the embryo?

Causes of fetal fading

The cause of a missed pregnancy may be:

• Chromosomal error;
• Antiphospholipid syndrome, which consists in a complex of disorders in which antibodies are formed in the body with its own phospholipids.
• Anembryony;
• Rhesus conflict;
• Hormonal disorders;
• Infectious diseases;
• Bad habits, including not only smoking or alcohol, but also coffee;
• Over/underweight;
• Taking hormonal drugs;
• Pathology of the uterus;
• Pregnancy with IVF.

According to statistics, the most common cause of fetal fading in early pregnancy is a genetic failure that affects the development of the embryo. Given the fact that the most important processes associated with the formation of the main systems, as well as internal organs, occur in the early stages of pregnancy, it is chromosomal errors that become fatal for the child at this time.

Unfortunately, gene pathologies can occur in the embryo even when the parents are absolutely healthy. Most often, for this reason, fetal fading occurs during the period from 2 to 8 weeks. A frozen pregnancy is less common after the 13th week.

What are the signs of a missed pregnancy?

Women who are at risk of fetal fading are concerned about how to determine the death of the embryo. After all, very often this pathology is completely asymptomatic. A woman may not feel pain or any change in well-being. A miscarriage can occur after several days or weeks after the death of the embryo.

Suspicion of a stop in the development of pregnancy may occur in the following cases:

• The beginning of bleeding;
• Pain in the lower abdomen, back;
• Abrupt cessation of the symptoms of toxicosis present (not in all cases);
• An increase in temperature above 37.5 0 С (only with the development of an inflammatory process);
• The disappearance of soreness of the chest.

However, do not immediately panic if you find one or more of the above symptoms. They can also occur during normal pregnancy. The main thing is to let the obstetrician-gynecologist observing you know about the appearance of complaints.

Signs of a missed pregnancy in the first trimester

First trimester

In different semesters, fetal freezing has distinctive symptoms. In the first trimester, toxicosis may suddenly stop (in about a day).

There is softening of the mammary glands. This symptom is noticeable to a woman, because from the moment the baby is conceived, there is an increase, soreness of the mammary glands. At the same time, this symptom remains doubtful, like any other (except for ultrasound, blood for hCG).

Decrease in basal temperature as a result of a decrease in the amount of progesterone. An error in the results occurs in the case of illness, taking hormonal drugs.

The absence of an embryo during an ultrasound examination. But ultrasound can also be wrong. It is recommended to undergo it after 5-6 weeks, because at this time the fetal heartbeat is clearly visible. Experts advise to wait with the cleaning of the uterus and conduct a diagnosis in 1-2 weeks.

Second trimester

The main sign of a non-developing pregnancy is the cessation of baby movements. Of course, you should not worry if the child does not move for a day or a day. If they have not been observed for a longer time, go to the doctor. So you get rid of unnecessary worries. The resolution of your worries is to check the baby's heartbeat with an obstetric stethoscope.

The allocation of a significant amount of colostrum, and after a while, milk. These symptoms appear for more than 25 weeks. But if there are no others besides this symptom, you should not worry. In the presence of fetal movements, this is simply the preparation of the body for breastfeeding.

Stopping the growth of the uterus.

Ultrasound diagnostics for suspected miscarriage

A missed pregnancy is never diagnosed by a specialist only by the presence of the above symptoms in a pregnant woman. A woman must be prescribed an additional examination. Since ultrasound diagnostics is considered the most effective way to diagnose an embryo development halt, it is precisely this that is recommended for a pregnant woman to undergo.

Ultrasound will allow not only to determine / refute a frozen pregnancy, but also in case of fetal death, to establish the period of its fading. Doctors prescribe diagnostics only after 6-7 weeks of pregnancy. When examined at earlier stages of embryo development, the information obtained through ultrasound may be unreliable.

The detection of a missed pregnancy at a very early date is true in the following cases:

• The embryo was not found, although the size of the fetal egg is more than 20 mm. In this case, the diagnosis of anembryony is made. In the normal course of pregnancy, already at the 7th week, the size of the embryo reaches 20 mm;
• The absence of cardiac activity of the embryo, the size of which reaches 16 mm (with transvaginal examination) or 25 mm (with transabdominal examination).

There are times when the doctor doubts the accuracy of the results. Then the specialist prescribes a second examination after a week or two. The quality of the results is influenced both by the qualifications of the examiner and the quality of the technique. On older ultrasound machines, a misdiagnosis can be made because it may not pick up the heartbeat of the embryo.

Ultrasound errors

Very often, a woman is not even aware of the fading of the embryo. Coming to the next scheduled ultrasound examination, a pregnant woman can be shocked by such a diagnosis. There are times when the diagnosis was made erroneously. Of course, for doctors, this is another diagnosis, but for a woman who is expecting a child, this is just a disaster.

If the doctor, after fixing the complaints of a pregnant woman, characteristic of a missed pregnancy, makes a hasty diagnosis, do not rush to clean. An experienced specialist will definitely prescribe an ultrasound to confirm the death of the fetus. In the early stages, everything is much more complicated, but thanks to modern technology and the qualifications of gynecologists, confirmation / refutation of fading is real.

If your health allows you to wait - do not rush to clean the uterus. There were cases when doctors were wrong, and women gave birth to healthy children, without any pathologies. The most accurate information about the probable death of the fetus can be found on an ultrasound scan performed at 6-7 weeks of embryo development. At this time, its size is large enough and the heartbeat is clearly audible.

It is necessary to undergo an ultrasound examination on new equipment, since old ultrasound machines may not notice the work of the heart of the embryo. Such an error can cost the life of your baby.
