Anembrioniya is a pathology that is manifested in pregnant women in the absence of a fetus inside a CVS, continuing growth and development. Evolution of an empty gestational sac asymptomatic. The main signs of a developing pathological process detected after interpretation results of the study of the dynamics of hCG levels: at anembrionii lagging behind its parameters from the norm growth.
As the level increases
Normally developing trophoblast should produce sufficient hormone hCG. Its concentration in the blood serum of a pregnant woman and dynamic changes are used by doctors as a criteria, reflecting the development of the ovum and its functional activity.
Physiological pregnancy accompanied by a process for producing hCG which carried primitive trophoblast on day 2 after implantation.
The table shows the rate of growth index during the period after ovulation:
| Days after ovulation | hCG min | hCG average | hCG max |
| 7-14 | 2-29 | 4-105 | 10-170 |
| 15-22 | 39-1050 | 160-2680 | 270-4900 |
| 23-30 | 1400-10500 | 3550-16500 | 6200-40000 |
| 31-38 | 11500-22000 | 19500-45000 | 60000-87000 |
| 39-42 | 23000-28000 | 51000-65000 | 93000-12800 |
The maximum concentration of hormone (100-132 IU / ml) was observed during the 6-10 weeks of pregnancy is not complicated pathologies. Starting from 11 weeks is considered normal decline.
To date 33 ± 2 weeks parameter increases again to approximately 35 IU / ml.
When present anembrionii fertilized egg grows, while hCG is produced and increases its concentration in blood.
Serum hCG patients anembrioniey in the first trimester behind the norm of 8.6 times in the second - 3.3 times, for a period of 28-30 weeks of lag is reduced to 2.7 times.
Why growing importance
HCG in the development of an empty gestational sac will grow because for the production of the pregnancy hormone is responsible chorion, which is present and even actively increased in pregnant women with diagnosed sizes anembrioniey. However, the growth rate is slowed down in such cases due to the fact that the embryo within the cavity defined by the membranes is absent.
If a doctor using ultrasound apparatus can not accurately tell whether the embryo is alive because of its fuzzy imaging or because of that he is not formed, the medical practice to perform control tests on hCG with a 2 day intervals. The emptiness of the ovum will not be able to double the performance of the hormone every 2 days, as is the case in a pregnancy without complications developing a similar pathology.
Proven anembrioniya entails the need for a medical abortion or surgery to cleanse the uterus of an empty CVS. Therefore, the slow growth of hCG can not be grounds for termination of pregnancy. Only after 2-3 presumptive diagnosis of ultrasound procedures can be confirmed definitively.
If the index does not grow
Stagnating levels of hCG hormone and the full confidence Medical ultrasonography in the absence of live fetal ovum, which developed evidence of pathology, and it could no longer continue with the pregnancy.
In some cases, the woman's body spontaneously aborts anembrioniyu. Miscarriage occurs, in which the uterus gets rid of empty CVS.
The majority of women who become pregnant abnormal fertilized egg can continue to grow for an indefinite time, threatening the life of the mother failed. Patients anembrioniey shown to terminate a pregnancy.
Blighted ovum whose age does not exceed 6-7 weeks, could get out of the uterus by a medical abortion. At a later date doctors perform curettage - a surgical abortion.
