Prenatal (antenatal) screening – is a set of laboratory and instrumental investigations to detect any fetal abnormalities before birth.
The first expert 7-week ultrasound is done to detect a pregnancy. During the procedure, a doctor determines whether a woman is pregnant and gestational age, checks the correct position in the uterus.
At this stage of pregnancy, pregnant women undergo the combined OSCAR test that allows calculating the risk of fetal chromosomal abnormalities, as well as possible obstetric complications, such as high blood pressure, preeclampsia, preterm birth and other pathological conditions in women.The OSCAR test includes:
At this stage of pregnancy, pregnant women undergo maternal serum AFP screening to assess possible fetal neural tube defects.
Routine expert ultrasound to make a detailed assessment of fetal anatomy to exclude the major fetal growth abnormalities.
In the second trimester, except detecting major fetal growth abnormalities, a doctor can predict the signs of increased risk of preterm labor, early preeclampsia, intrauterine growth restriction and others.
Doppler velocimetry to evaluate fetus wellbeing before the onset of labor.
At this stage of pregnancy, it is possible to detect major fetal growth abnormalities, which are subjected to successful fetal surgery or surgery after birth.
Fetal monitoring using a cardiotocograph (CTG) or Doppler velocimetry 1 time in 2 weeks.
In the third trimester, a doctor examines not so much the fetal abnormalities, as signs and symptoms of increased risk of preterm labor, early preeclampsia and intrauterine growth restriction.
Doctors of LELEKA Maternity Welfare Center use advanced methods for monitoring of pregnancy of any complexity, and especially high-risk pregnancy.Fetal karyotype and genetic testing using invasive and non-invasive methods in the maternity hospital are as follows:
1Ultrasound cervicometry (measurement of the cervix) is recommended for women with recurrent pregnancy loss and previous preterm delivery starting at16 weeks of gestation. Ultrasound vaginal cervicometry is a safe and effective way of assessing risk for preterm birth that makes it possible to take measures that can delay delivery.
2In women with preeclampsia and other hypertensive disorders, periodic assessment of fetal wellbeing using Doppler velocimetry is recommended.
3In women with gestational diabetes, special attention is paid to monitoring of fetal growth and wellbeing. Starting at the 28th week of pregnancy, ultrasonic fetometry and control of amniotic fluid volume are performed every 4 weeks (32, 36 weeks of pregnancy).
LELEKA Maternity Hospital treats women with high-risk pregnancy, who require an individual approach, with special care and concern.
