Anembrionia - is there a pregnancy, or is it, nevertheless, not?

Anembryonia is a special case of missed abortion when the death of the embryo occurs so early that the egg of the egg is empty. Anembrionia occurs in 15% of all early termination of pregnancy. What it is?

In case of an embryo, either the embryo does not set up at all, or it dies at such an early date that nothing is found in the cavity of the ovum. This diagnosis requires repeated ultrasound, because quite often there are cases in which anembryonia was not confirmed by ultrasound after a week or two. The reason that the embryo was not seen may be that the examination period was too early, and then the hope that you will still become a mother, of course, is.

Causes of anembryony

If a woman is diagnosed with anembryonia, the reasons most often in the fact that a vicious conception occurred, there was a incomplete zygote, or the embryo was influenced by harmful factors that killed it. Sometimes this happens in a perfectly healthy woman and the causes cannot be established.

The most common factors are:

1. SARS and other infectious diseases of the mother in the first weeks of pregnancy.

2. Intoxication and poisoning, taking embryotoxic drugs prohibited during pregnancy, alcohol, smoking.

3. Radiation exposure

4. Stress and Exercise

5. Overheating or high temperature in the early stages.

6. Hormonal disorders in mom

Ultrasound diagnosis of anembryonic

As already mentioned, this diagnosis always sounds with an ultrasound examination. No other way to put it. The ultrasound doctor sees the fertilized egg with a cavity, but does not see the embryo and the heartbeat.

As you know, with ultrasound in the early period in the cavity of the ovum should be two formations, the yolk sac and next to it the embryo. Yolk sac during anembryony may be determined, but the embryo itself is not visible. If the ultrasound was done very early, a mistake is possible, so it is worth repeating it after a week or two.

HCG with anembryonic

How HCG grows during anembryonic infection may not be indicative at all. The fact is that this hormone of pregnancy produces the chorion, that is, the fetal membranes, and the fertilized egg is present during anembryonic infection, and these are living cells, of course, the hCG level during anembryonic infection can remain high and even grow. However, the development of this pregnancy is in any case pathological, and therefore the growth of hCG in anembrionia is slowed down.

If you suspect this diagnosis, your doctor will prescribe you control tests for hCG with an interval of 2 days to see if hCG is growing. With anembryonic infection, there will not be a characteristic hormone level doubling for a normally developing pregnancy every 2 days.

Symptoms and signs of anembryony

Like a normal pregnancy, anembryonia is accompanied by characteristic changes in the mother's body. Since fetal membranes are present and hormones are produced, you can experience all the symptoms of a normal pregnancy.

Signs of anembryonic infection, which could indicate that the child is no longer developing, are absent, there may be all the usual symptoms, such as delayed menstruation, chest engorgement, drowsiness, weakness, irritability. Even toxemia with anembryonia can be the most common, quite strong and pronounced.

The basal temperature in anembrionia remains elevated, and the expectant mother can never guess that there is no longer hope for motherhood. Only ultrasound allows to suspect this pathology, no other way to diagnose anembryonia is impossible.

Only sometimes the body reacts with a non-developing pregnancy like an embryonic miscarriage, the body itself gets rid of the deceased embryo. Then there are signs of threatened interruption, such as lower abdominal pain, spotting, and the woman goes to the doctor.

Anembryonic treatment

If a woman has heard such a sentence as anembrionia, treatment is only one, the pregnancy should be terminated as soon as possible. Of course, it is possible in some cases of anembryonic misdiagnosis, so the doctors are not in a hurry, prescribing a second ultrasound and waiting for some time.

Miscarriage in anembryonic infection sometimes happens spontaneously, but still most often the pregnancy can continue indefinitely, and it must be interrupted. For a very short period of time, it is possible to interrupt with pills, but more often doctors resort to scraping, in the people this is called cleaning. The procedure resembles a normal abortion. Scraping for anembryonic make in the gynecological department under brief anesthesia. Then the woman is prescribed antibiotics and is discharged home a few days later.

Planning for pregnancy after anembrionia

If such a misfortune has happened in your life, pregnancy planning after anembrionia should be postponed for at least 6 months.

Prevention of unwanted pregnancy is carried out with the help of hormonal contraceptives. You and your husband need to be examined before the new pregnancy. Examination after anembryonic infection makes it possible to identify all possible diseases and abnormalities in the state of health that could lead to the fading of the embryo. If there is an objective reason, and the expectant mother does not receive adequate treatment after anembryonia, everything can happen again.

Anembrionia is indeed repeated, and that would not happen, the pregnancy should be planned.

Why did this happen to me?

A frequent question that torments every woman passing through it. It's really hard to realize that your long-awaited, beloved child died inside of you. Do not torment and do not torment yourself, take what happened as a boon. A deliberately sick, not a full-fledged embryo dies, this baby would be born and perhaps could not live, or would suffer greatly, nature took care of it before. And you will be fine, do not give up and the next time fate will give you a healthy, strong baby, everything will work out for you, the main thing is to want that much.

The answer to this question can be found in the instructions for any medication, as in the column "contraindications" are always prescribed situations in which it is better not to use it or require prior consultation with a specialist, a sensitivity test.

So, to avoid the occurrence of varicose veins or to prevent the progression of the disease during pregnancy, two basic rules should be adopted:

  • to minimize the load on the lower body (especially on the legs),
  • facilitate the flow of blood.

Causes and signs of anembryony

A cherished positive test in the hands, joy and happiness, unfortunately, often end in bitter tears on ultrasound.

A woman hears a diagnosis of embryonia and cannot understand how this is possible, because there were all signs of pregnancy, confirmation of a local gynecologist, and the tests do not lie. The state of distress and grief does not allow to adequately assess the situation and understand it.

Similar, as it is not terribly aware, can happen to each of us, so we will try to explain the causes of anembryonia, how to prevent and detect it in time.

What is it and why is it happening?

Anembrionia is a frozen, non-developing pregnancy. A malformation occurs due to the fact that the ovum, although reinforced to the uterus, nevertheless does not contain an embryo. It happens that the embryo has formed, but stopped its development.

Statistics suggest that 15 percent of women are similar. And those who have ever experienced a stalled pregnancy have every chance to continue to bear and give birth to a healthy baby. But the mothers of small crumbs are not insured, he anembryony in the subsequent pregnancy.

Most often, the frozen pregnancy occurs at the beginning of the first trimester, for up to six weeks, sometimes a little later. After the fertilization of the egg by the sperm cell, the cell division begins. Some of them become an embryo, the rest form fetal membranes and the placenta. So, sometimes those cells from which the embryo was supposed to form, stop dividing, while others continue to divide, as expected. As a result, the ovum continues to grow in size, but in fact, it is empty.

This is the main trick of a missed pregnancy - the woman does not even suspect what is happening inside. Pregnancy hormones continue to be produced, thereby deceiving the organism.

It happens that the body reacts to an anemionic disease by spontaneous miscarriage. Of course, then the woman will most likely feel pain and detect bloody discharge (after which you should immediately seek medical help). But in most cases, a woman fully feels all the pleasures of pregnancy in the form of toxicosis, breast engorgement, uterus enlargement, absence of menstruation, and so on.

The surest sign of an embryony (not counting ultrasound) will be a decrease in the level of hCG. If you are worried, then this analysis can be taken in any laboratory every three days. For the rest, a frozen pregnancy does not manifest itself.

Thanks to new technologies and methods of examination, doctors were able to identify some of the most likely causes of embryo.

There are several external factors.

An acute infection that a woman could have had at the time the embryo was laid out could cause a missed abortion. The virus can directly hit the embryo itself or significantly worsen the condition of the future, causing a rise in temperature, thus having a damaging effect on the development of the embryo.

Pyelonephritis pneumonia (any other acute bacterial infection) implies the use of antibiotics as a treatment, which in turn may negatively affect the development of the embryo.

Toxic substances cause disruption of the work of the whole organism of the mother and have a huge load on all internal organs, the uterus and the embryo just started its development.

Is it worth talking about the destructive effects of radiation on humans? What to say otakom process as the birth of life.

Harmful habits such as smoking, alcohol addiction or drug addiction significantly increase the risk of anembryonia.

Genetic disorders are the most common cause of missed abortion.

Changes in the parent germ cells can also lead to fetal death at the most early stages of development. For example, if a viable, healthy sperm cell is found with a pathological egg or vice versa. An incorrect chromosome entails a detrimental effect on the embryo. The same radiation can cause genetic changes and cause the body to reject the fetus from the mother.

Hormonal disorders in a woman’s body can also lead to anembrionia. It is precisely through this that hormonal leveling is the basis of the foundations in the centers for the restoration of the reproductive function of the family.

Diagnosis of missed abortion and subsequent actions

Anembryonia is diagnosed exclusively by ultrasound. And never conclusions are made only on a single result of ultrasound. The main task of both mothers and doctors is to preserve pregnancy, it is not uncommon when, because of an unqualified doctor or device, there are not enough sensitivities. Any competent doctor will not make hasty conclusions and will invite you to undergo a re-examination after a few days or a week. Most likely, it will be extremely difficult in moral terms, but you need to make sure that there is really no embryo in the fetal egg or, on the contrary, good news.

However, there are rules that state that if the size of the ovum is more than 20 mm, the embryo is not visible, in this case the highest probability of anembriony.

Additionally, an analysis of the level of human chorionic gonadotropin (hCG) is carried out. If the indicators are low, then with the help of them it will be possible to calculate at what time the death of the embryo occurred.

After the diagnosis is confirmed, you will be offered two choices. Most likely, it will be scraping the uterus (cleaning), removal of the ovum. And the second option is a medical abortion, if we are talking about the shortest term (in Russia, only cleaning is possible).

At this, your life does not end, moreover, there is every chance of a quick conception and a healthy pregnancy with a happy birth. But do not hurry and plan right away anembryony.

Should give time to the body recovery. With the help of a number of drugs and vitamin complexes prescribed by the doctor, the uterine mucosa will recover. It is usually recommended to be protected for about six months after missed abortion.

Accurately determine the cause of embryonia is almost impossible. Doctors can only guess why this happened, looking at external factors. Alas, the results of histopathological research here also will not help, since for the time being the curettage the division of the cells has already stopped.

A more detailed diagnosis and treatment is prescribed only in repeated cases of miscarriage.

We hope that you will not have to face such a diagnosis, but if this happens, you should remember that the next attempt will be successful, and you must be the best mom.

During pregnancy, pregnancy often occurs due to fetal abnormalities and the body rejects the embryo at the very beginning of development, thus giving you the opportunity to bear and give birth to a healthy and strong baby, which we wish you.

Fetal egg without embryo: signs and symptoms

Even after the fertilized egg stops developing, the body continues to prepare for the bearing of the child. Preparation is manifested in the increased production of hormones, which causes early symptoms of pregnancy (morning sickness, chest pain and bloating). The growth of hgch during anembryonic infection leads to the fact that already 7 days after fertilization, the pregnancy test will show 2 strips.

There are the following obvious signs of anembryonia:

  • severe vaginal bleeding, similar to heavy periods,
  • painful cramps in the abdomen (this symptom may also indicate other complications, including ectopic pregnancy, so an urgent need to consult a doctor),
  • a couple of weeks after a positive test, a negative result appears on the strip (hgch with anembryonia stops producing within a few days after implantation),
  • Ultrasound on the 7th week of pregnancy, showing the ovum without an embryo.

Diagnosis and signs of anembryonic ultrasound

If symptoms of anembryonic infection appear, transabdominal or transvaginal ultrasound is prescribed. The diagnosis of anembryony is made when there is no hope, and the doctor clearly sees one or more of the following symptoms:

  • It’s impossible to clearly identify an embryo with a transabdominal ultrasound study,
  • the contour of the ovum in the picture is fuzzy or has broken boundaries,
  • The picture shows only a homogeneous fluid inside the ovum (without blackouts and points).

In the early stages, when it seems that symptoms of anembrionium appear, ultrasound may not reveal any abnormalities. After all, a healthy embryo is not always visible in the ultrasound image in the first weeks after fertilization. Therefore, even if there are reasons to suspect an embryonic disease, it is necessary to wait until the amniotic egg grows. Diagnosis and treatment of anembryonic infection do not begin until the amniotic egg reaches a size of 25 mm. If anembryonia is confirmed, duphaston is prescribed immediately after the termination of the pregnancy.

How does this manifest itself?

Anembrionia does not have its own clinical symptoms, all appearing disorders are usually associated with the threat of termination of such a pathological pregnancy. And the warning signs include the presence of clinical manifestations of relative progesterone deficiency, which creates the prerequisites for spontaneous abortion. Therefore, lower abdominal pains and bloody discharges can become a reason for going to a doctor, with anembryonic infection, they can appear on almost any term during the 1st trimester.

But often, a woman learns about the existing pathology only when screening an ultrasound scan for a period of 10-14 weeks.

Varieties

There are several variants of empty fetal egg syndrome:

  • Anembrionia type I. The embryo and its residues are not visualized, the size of the ovum and uterus do not correspond to the expected duration of pregnancy. The diameter of the egg is usually not more than 2.5 mm, and the uterus is increased only to 5-7 weeks of gestation.
  • Anembrionia type II. There is no embryo, but the fetal egg and uterus correspond to the gestational age.
  • Resorption of one or more embryos in multiple pregnancies. At the same time, normally developing and regressing ovum eggs are visualized. According to this type, anembrionia often occurs after IVF, if several embryos have been transferred to a woman.

Все эти разновидности определяются лишь с помощью УЗИ, характерных клинических особенностей они не имеют.

Что делать?

Подтвержденная анэмбриония является показанием для искусственного прерывания беременности. It does not take into account the period of gestation, the well-being of the woman and the presence of signs of a possible spontaneous abortion. An exception is the situation when the second gestational anembrionia is diagnosed during multiple pregnancy. In this case, wait-and-see tactics are undertaken, assessing the development of a surviving embryo over time.

Interruption of missed abortion is carried out only in the hospital. After the procedure of evacuation of the ovum, the woman should be under medical supervision. In many cases, after it, additional medication and sometimes physiotherapy treatment is prescribed, aimed at normalizing hormonal background, preventing inflammatory and hemorrhagic complications, and eliminating the identified infection.

For carrying out medical abortion with this pathology it is possible to use several techniques, the choice depends on the technical equipment of the medical institution and the period of gestation. Can be used:

  • medical abortion - termination of pregnancy with the help of hormonal drugs that provoke endometrial rejection together with the implanted fetal egg,
  • vacuum aspiration of uterine cavity contents,
  • curettage is an operation involving the mechanical removal of the ovum and endometrium with a special tool (curette) after forced expansion of the cervical canal with bouges.

Medical abortion with anembryonic infection is possible only for a period of 6-8 weeks. In the later stages of gestation, preference is given to mechanical methods, which requires the use of general anesthesia. The choice of the method of artificial abortion depends on whether the stomach hurts after an abortion, the duration of the rehabilitation period, the likelihood of early and late complications.

Examination after artificial abortion necessarily includes ultrasound control. This allows you to confirm the complete evacuation of the fetal membranes and endometrium, to eliminate the undesirable effects of abortion in the form of hematometers, perforations and endometritis.

Can anembryonia recur? Can I still have children? These questions concern all patients who have undergone this pathology. Fortunately, in most cases the condition does not recur, the woman subsequently succeeds in successfully getting pregnant and carrying out the child. But at the same time it belongs to the risk group for the possible development of complications of pregnancy and childbirth. Therefore, in the first trimester, she is usually assigned a dynamic ultrasound monitoring of the development of the ovum, determination of the hormonal profile and assessment of the state of the hemostatic system.

Pregnancy after anembryony is theoretically possible already in the next ovarian-menstrual cycle. But it is desirable to give the body to recover. Therefore, re-conception planning is recommended to begin no earlier than 3 months after the induced abortion. If he proceeded with complications, the rehabilitation period in compliance with reproductive rest extended for up to six months. If a woman has chronic endometritis and various infections, 2 months after the end of the treatment, control tests are carried out and only then possible terms of re-conception are determined.

To prevent pregnancy, preference is given to the barrier method and hormonal contraception. The selection of funds is carried out individually. Intrauterine devices immediately after suffering a frozen pregnancy are not used to avoid the development of endometritis.

Service prices

Anembrionia is often asymptomatic, all signs of normal pregnancy: toxicosis, uterine enlargement, swelling of the mammary glands, lack of menstruation, persist. Pathology can be identified by planned ultrasound, which visualizes the absence of an embryo in the fetal egg or an early arrest of its development. Spontaneous miscarriage sometimes becomes a sign of anembryonic.

Other reasons:

  • defeat of the embryo by acute viral or bacterial infections at an early stage of pregnancy, inflammation,
  • the influence of radiation or toxic substances at the stage of laying the fetus,
  • hormonal disorders,
  • bad habits: smoking, alcohol or drug use.

Diagnosis of anembryonic

Reliable diagnosis of anembryonia is possible with a combined approach. A gynecological examination may determine if the size of the uterus does not match the gestational age. So the uterus with anembryony is always smaller than the intended period requires. An ultrasound examination of the pelvis can reveal the absence of a fetal heartbeat or an egg of the fetus without an embryo. A hormonal blood test will confirm or refute the stopping of the progressive increase in the numbers of the hCG pregnancy hormone (choriogonic gonadotropin) characteristic of normal pregnancy.

Pregnancy after anembryony

Fortunately, after a single embryonic pregnancy, the vast majority of women do not have problems with the onset and gestation of a subsequent pregnancy. However, couples with a history of anembrio need to approach conception more carefully and carefully. So, the next pregnancy should be planned no earlier than 3-6 months after a previous failure. Before conceiving it is necessary to go through the following stages of preparation:

  • medical examination, correction of identified abnormalities,
  • health improvement of the spouses (balanced nutrition, vitamin therapy, elimination of harmful factors),
  • psychological help.

FACT: Up to 90% of patients who have had a one-time pregnancy loss in the past safely bear and give birth to healthy children.

If miscarriages happened 2 or more times, we are already talking about habitual miscarriage. In this case, the couple requires more detailed examination and treatment.

Prevention

There is no specific prophylaxis for anembryonic infection. A woman must maintain a healthy lifestyle and eat right before she becomes pregnant, and also give up heavy physical exertion and do not miss a visit to an obstetrician-gynecologist. This disorder has no consequences, re-pregnancy after anembryonia ends with the birth of a baby. There is a possibility of establishing a similar diagnosis during a subsequent pregnancy, so IVF may be the most effective way to have a baby. If this disorder is repeated several times, both partners will be examined by a geneticist.

If you think you have Anembrionia and symptoms characteristic of this disease, a gynecologist can help you.

Filariasis - a tropical disease, the development of which is observed as a result of penetration into the human body of parasitic worms, called filarias. In the medical literature, this pathology is also called elephant disease. Filariasis has the opportunity to become infected both from a sick person or animal, and as a result of an insect bite. After penetration into the human body, the worms first settle in the lymph nodes and vessels, so the disease also has another name - lymphatic filariasis. Also, worms penetrate into the cavity of the human body, genitals, eyeballs and under the skin.

Pneumonia is an infectious inflammation of the lungs that affects the alveoli or other lung tissue. Pneumonia can occur from various pathogens - bacteria, viruses, fungi. Therefore, there are a large number of types of pneumonia, each of which has its own symptoms and characteristics of percolation. In the lungs of a healthy person there is always a certain amount of certain bacteria. And in most cases, the immune system fights well with them. But when the body is weak and can not cope with them, there is an active development of pneumonia.

A lupus is a disease of an autoimmune type, during which the defense system that the human body has (that is, its immune system) makes an attack on its own tissues while ignoring foreign organisms and substances in the form of viruses and bacteria. This process is accompanied by inflammation and lupus, the symptoms of which manifest themselves in the form of pain, swelling and tissue damage throughout the body, while in its acute stage, provokes the emergence of other serious diseases.

Lymphocytic leukemia is a malignant lesion that occurs in lymphatic tissue. It is characterized by the accumulation of tumor lymphocytes in the lymph nodes, in the peripheral blood and in the bone marrow. The acute form of lymphocytic leukemia most recently belonged to "childhood" diseases due to its susceptibility to predominantly patients aged two to four years. Today, lymphocytic leukemia, whose symptoms are characterized by its own specificity, is more common among adults.

Paraproctitis is a purulent inflammation that forms in the fatty tissue that surrounds the anal sphincter and the rectum. Paraproctitis, the symptoms of which are determined depending on the form of the disease, after hemorrhoids, is one of the most frequent diseases that occur in the rectal area.

With exercise and temperance, most people can do without medicine.

Is it possible to prevent anembryonic infection?

The sad news is that really little can be done to eliminate the possibility of this pathology. Genetic factors may influence, it may just be a bad case, or the cause may be the poor quality of the sperm and / or egg. Most women at least once in their lives suffer from this problem, and those who have it on a more regular basis should be thoroughly examined by doctors. A healthy lifestyle is the only recommendation to increase the chances of a healthy pregnancy. Read more about avoiding miscarriage.

What is the treatment for anembryonic?

  • Dilatation and curettage. You can choose this procedure, which is also commonly called scraping. At the same time, the cervix is ​​dilated and its contents are physically removed - the egg cell is removed along with the remaining tissue. Often this procedure is chosen by women who would like to examine the material in order to find the cause of anembryonia, as well as those who seek to complete the unsuccessful pregnancy as quickly as possible.
  • Misoprostol. This drug speeds up the process of ridding the uterus of unnecessary tissue (although it may take several days to complete the process). Drug therapy can also be accompanied by rather unpleasant side effects, such as bleeding and cramping.
  • Wait until everything happens naturally. The third option is to allow nature to control what happens to your body and generally refuse any drugs or surgery. The doctor may advise or prohibit this option depending on the state of health.

Regarding which of the options to choose, the doctor will make recommendations for each specific case, although the final decision is always left to the patient. Most likely, the doctor will advise you to wait up to three menstrual cycles before trying again to conceive a child. Find out more about when you can try to get pregnant again after miscarriage.

Two types of non-developing pregnancy

Based on the results of ultrasound, you can determine two types of non-developing pregnancy: empty fertilized egg (anembryonia) and fetal death.

Anembryonia is the absence of an embryo in the fetal egg.

They say about the death of the embryo, when it developed normally at the beginning of pregnancy, but then died for some reason. If this happened recently (several days after death), the embryo and egg have the usual shapes and sizes, but there are no signs of fetal life. This condition may not be accompanied by clinical symptoms of threatened abortion.

Causes of non-developing pregnancy

1. Genetic and chromosomal abnormalities of the embryo are the main cause of early losses (80%).

2. Malformations of the female genital organs (for example, doubling of the uterus, full uterus septum, two-horned uterus, etc.).

3. Pathological conditions of the mucous membrane of the uterus of a woman (endometrial atrophy, Asherman syndrome - intrauterine synechia (adhesions, adhesions).

4. Disruption of the blood coagulation system: hereditary thrombophilia.

5. Other reasons.

According to the American community of obstetricians and gynecologists (ACOG), the link between early pregnancy loss and two risk factors is most reliably proven:

1. The older and late reproductive age of the mother. 2. A large number of previous miscarriages (3 or more).

Reproductive capabilities also reduce chronic maternal diseases, both gynecological (for example, endometriosis) and general (diabetes, arterial hypertension, obesity).

Also risk factors include impaired reproductive health of the sexual partner. They are divided into manageable (nicotine addiction, drug addiction, low or high body mass index) and uncontrollable (older reproductive age of parents, stress).

Examination after non-developing pregnancy

Immediately after spontaneous miscarriage or removal of the fetus, the karyotype of the ovum is examined. If there are three or more losses, it is recommended to investigate the karyotype of the parents.

Karyotyping is a genetic analysis that studies quantitative and structural chromosome abnormalities.

When anatomical disorders are detected, careful ultrasound examination and hysteroscopy are recommended with further elimination of defects (if possible). In rare cases, in the presence of thrombosis in the history of the patient and her immediate family, a hematologist's examination is recommended.

In preparation for the subsequent pregnancy

There are situations that can be foreseen, but it is very difficult to change. These include non-developing pregnancy. Unfortunately, it is impossible to completely eliminate the risk of a non-developing pregnancy, but a non-developing pregnancy, although a psychologically difficult factor, does not exclude the normal course of subsequent pregnancies.

You will need a recovery period, after which it makes sense to visit the doctor and be sure to restore the mental background.

1. folic acid intake - 400 mcg daily (as recommended by WHO) for 3 months. before the intended pregnancy

2. lifestyle changes (weight loss, smoking cessation, etc.),

3. identification and treatment of associated chronic diseases (hypothyroidism, hypertension, diabetes, etc.).

Everything will necessarily be normal if the pregnancy is carefully planned and takes place under the constant supervision of a doctor.

What is anembryony

The absence of a developing embryo in the fetal egg is called an embryonic, or empty fetal egg syndrome. This pathology can be diagnosed both in first-pregnant women and those who already have healthy children. Non-developing anembryonic type of pregnancy is caused by the termination of the division and differentiation of embryoblast cells. As a rule, fetal development disorder occurs in the first four to five weeks of gestation under the influence of various factors.

Often, the causes of empty fetal egg syndrome remain unclear, and it is possible to determine a presumptive etiology on the basis of anamnesis. A histological or genetic study of aborted tissues may reveal pronounced pathologies, but such a study is rarely performed and is indicated with a woman’s obstetric history (past miscarriages, missed pregnancies). Currently, the following causes of anembryony are distinguished:

  1. Genetic anomalies. They cause anembrionic pregnancy in almost 80% of cases. As a rule, genetic pathologies are associated with multiple chromosomal abnormalities incompatible with life. Nonviable combinations of the genetic material of the parents or mutations in the zones that are responsible for embryogenesis and fetal development are possible.
  2. Acute viral / bacterial diseases that occur in early pregnancy and cause damage to the tissues of the embryo, the trophoblast. The most dangerous are the causative agents of measles, rubella, influenza, etc.
  3. Persistent (latent) infections of the internal genital organs, resulting in chronic endometritis. Pathology often occurs without severe symptoms and is found after an unsuccessful pregnancy.
  4. Radiation effects on the embryo in the first weeks of gestation.
  5. Exogenous intoxication. These include taking medicines with a pronounced embryotoxic effect, use of drugs, alcohol, smoking, occupational hazards, which include the effects of industrial and agricultural toxins, poisons.
  6. Endocrine disorders in pregnant. The most critical for the development of the embryo is the lack of progesterone, which leads to an abnormal implantation of the ovum.
  7. Чрезмерные физические нагрузки, стрессовые ситуации, травмы. Приводят к нарушению кровообращения плода, истощению эндометрия и, как следствие, гибели эмбриона.

Признаки анэмбрионии на ранних сроках

The first signs that there is no embryo in the fetal egg can be tracked by a small change in the content of human choriotropic hormone. A gynecologist can suspect a non-developing pregnancy while evaluating the results of tests for hCG dynamics. The increase in the concentration of the hormone at the lower limit of the norm is the basis for further examination of a woman for anembryonic anemia using ultrasound.

Anembryonic pregnancy does not have its own clinical picture, all appearing symptoms are usually associated with the implantation of the embryo or the threat of miscarriage of a non-viable fetus. The warning signs include:

  • pains in the lower abdomen,
  • bloody issues,
  • swelling of the mammary glands,
  • toxicosis (nausea, fatigue, dizziness, headache, fainting),
  • increase in the size of the uterus,
  • lack of regular menstruation,
  • temperature rise to subfebrile values.

How long can you walk with her

If the gynecologist suspected an embryonic anemia in a woman earlier than 7-8 weeks and the patient does not complain of a significant deterioration (abdominal pain, fever, bleeding), then a wait-and-see tactic is recommended to rule out a medical error. Subject to the presence of a gestation period of more than 8 weeks, the absence of a fetal heartbeat on an ultrasound scan, an artificial interruption is indicated on the visualization of the embryo. For a long time, it is not recommended to walk with a woman diagnosed with anembryony, this increases the risk of complications after an abortion.

Medical abortion

Interruption of a non-developing pregnancy with the help of hormonal medicines (Mefipriston) is carried out for a period of up to 5-6 weeks. The procedure should be carried out in the clinic under the supervision of medical staff. A woman is given a pill and taken to the ward. After a few hours, the patient feels a pulling pain in the lower abdomen, and spotting comes out. After their termination, it is necessary to conduct an ultrasound examination.

Contraindications for medical abortion are endocrine diseases, malignant neoplasms and individual intolerance to the components of the drug. The consequences of the interruption, which was performed with the help of special preparations, are minimal in the early stages, and all possible complications (allergic reactions, endometriosis) are treatable.

Scraping uterine cavity

Before the operation in case of a non-developing pregnancy, the patient is prepared the cervix. This is necessary for its careful, gradual expansion, reducing the risk of trauma. For the preparation of used sticks of algae, which the day before the procedure is inserted into the cervical canal. Immediately prior to surgery, a woman is examined by a doctor to assess the size of the uterus, its location, performs the treatment of the external genital organs with disinfectant solutions and is injected into anesthesia.

Then the obstetrician-gynecologist expands the cervical canal with special tools and curettes the removal of the upper endometrium layer. During the procedure, uterine-reducing drugs (oxytocin) are administered intravenously. The operation itself lasts about 15–20 minutes. After the scraping, the following rehabilitation measures are carried out:

  1. Prescribing antibiotics to prevent infections.
  2. Acceptance of hormonal drugs for 3-6 months.
  3. Sexual rest for a month after curettage to prevent infection of the injured endometrium.
  4. Ultrasound study to exclude residual fetal membranes.

As with any surgery, after curettage there is a risk of developing some complications:

  1. Endometriosis. After curettage, the uterus mucosa is traumatized; therefore, the pathogen entering the uterus leads to the development of inflammatory processes. Symptoms of endometritis are:
    • pain in the lower abdomen,
    • increased body temperature
    • Persistent vaginal discharge.
  2. Bleeding. May begin during surgery, immediately after it or after a while. The reason may be a bad contraction of the myometrium, the remnants of the membranes of the ovum.
  3. Adhesions Due to the fact that curettage is a traumatic operation, there is a possibility of severe damage to the mucous membrane. In some cases, this leads to the formation of connective tissue accretions.
