The Department of Fetomaternal Medicine performs all necessary ultrasound examinations to assess the development and anatomy of the fetus, from the early days of conception to the end of pregnancy.

 

  1. Nuchal translucency ultrasound
  2. In the majority of cases, it is performed intrabdominally, at a specific time of pregnancy (gestational age between 11 weeks and 1 day to 13 weeks and 6 days).

    Objectives

    • Confirmation of the actual gestational age (it is often the case of women's unstable cycle, mistaken reports of the last period, women who conceived while breastfeeding and women who conceived in less than three months after the discontinuation of contraceptives)
    • Diagnosis of basic embryo abnormalities
    • Diagnosis of multiple pregnancy (chorionicity)
    • Determination of the risk of the fetus suffering from a chromosomal abnormality, e.g. Down's syndrome, etc
    • Nuchal translucency
    • In every fetus, fluid is accumulated in the neck area between the muscles and the skin. This presence of fluid is called nuchal translucency. The greater the nuchal transparency, the greater the risk for chromosomal fetal abnormalities or other problems, e.g. congenital heart disease.

    Nasal Bone Detection

      The presence of nasal bone at this gestational age reduces the risk rate for Down syndrome, while its absence increases it.

    • Tricuspid Doppler
    • Ductus venosus Doppler
    • Measurement of biochemical markers (PAPP-A, free β-HCG).

    Invasive Test

    • Trophoblast biopsy.

    Amniocentesis

    • The combination of all the aforementioned measurements is 95% accurate in the prognosis of fetal chromosomal abnormalities.

     

  3. Level 2 ultrasound (fetal anatomy scan)
  4. It is performed intrabdominally during the 20th-24th week of pregnancy.

    Objective

    • Detailed embryonic anatomy scan to exclude congenital malformations
    • Screening for intrauterine growth restriction
    • Determining the location of placenta
    • Amniotic fluid volume assessment
    • Fetal echocardiography
    • The embryo is checked for the presence of any anatomic markers that may increase the risk for chromosomal abnormalities
    • Estimation of the flow of uterine vessels to determine adequate placental perfusion and assess the likelihood of risk for residual intrauterine fetal growth or preeclampsia, which requires intensified pregnancy monitoring.

     

  5. 3rd trimester ultrasound (development scan)
  6. This ultrasound is usually performed during the 32nd week of pregnancy. Most pregnancies are progressing normally. At a small percentage, however, pregnancies will more frequently present complications in the third trimester, e.g. preeclampsia, gestational diabetes, Intrauterine Growth Restriction, etc.

    Objective

    • Growth check and measurement of possible fetal weight
    • Assessment of fetal movements
    • Doppler for assessing uteroplacental and fetal circulation
    • Amniotic fluid volume assessment
    • Evaluation of placenta appearance and location.
