ULTRASOUND CHARACTERISTIC OF EMBRYO, FETAL EGG AND CHORIONIC STRUCTURES IN PREGNANT WOMEN WITH MISCARRIAGE.

OBJECTIVE

The aim: The aim of the study was to assess the peculiarities of the formation and development of the fetoplacental system, to study the structures of the embryo, gestational sac, chorion in pregnant women with miscarriage.

PATIENTS AND

METHODS

Materials and methods: A comprehensive ultrasound examination of 50 pregnant women was carried out in the period from 5 to 16 weeks of pregnancy, of which 25 - with a history of miscarriage (main group), and 25 - with an unremarkable medical history (control group).

RESULTS

Results

We have identified the following echographic markers of adverse course and outcome of pregnancy in women with miscarriage in embryonic and early fetal periods:- lag of CRL of an embryo by 2 weeks and more at ultrasound examination in terms up to 9 weeks of gestation;- corporal or basal (near the stem of the embryo body) location of chorionic detachment with the formation of retrochorial hematoma with a volume of more than 25 ml;- pronounced progressive decrease in the volume of the gestational sac and amniotic cavity;- pronounced polyhydramnios with the presence of a coarse echopositive suspension in the amnioticcavity. The likelihood of spontaneous miscarriage and the formation of placental dysfunction is higher with the simultaneous detection of 2 or more echographic markers.

CONCLUSION

Conclusions

Ultrasound examination is necessary to assess the echographic parameters of the formation and development of the embryo and extraembryonic structures in the first trimester with a history of miscarriage in order to the subsequent choice of rational tactics of pregnancy management.
