In the Fetal-Maternal department all ultrasound tests necessary to evaluate fetal development and anatomy from the first days after conception to the end of pregnancy are performed.
1. Nuchal translucency ultrasound
This is mostly performed transabdominally.
It is performed at a specific period during the pregnancy (between 11 weeks and 1 day and thirteen weeks and 6 days).
• To confirm the true pregnancy age ( for women with an unstable menstrual cycles, erroneous last period reports, women who conceived during lactation and women who conceived in less than three months after stopping taking birth control pills)
• Diagnosing main fetal abnormalities
• Diagnosing multiple pregnancies (chorionicity)
• Determining the risk of the fetus presenting some chromosomal conditions (e.g., Down syndrome, etc.).
• In all foetuses, fluid is accumulated in the area of the neck between the muscles and the skin. This fluid accumulation is called nuchal translucency. The thicker the nuchal translucency the higher the risk of fetal chromosomal conditions or other problems such as congenital heart conditions.
Nasal Bone assessment
The presence of a nasal bone at this pregnancy age reduces Down syndrome risk whilst its absence increases it. Tricuspid valve
Doppler Venous vessel
Doppler Biochemical indicators (PAPP-A, free β-HCG)
• The combination of the above measurements attains 95% accuracy in predicting fetal chromosomal abnormalities.
2. Level 2 Fetal Anatomy Ultrasound
This is performed transabdominally from pregnancy week 20 to 24.
Comprehensive fetal anatomy screening in order to rule out as many congenital malformations as possible.
• Normal endometrial development screening
• Detecting the placental location.
• Amniotic fluid assessment
• Fetal echocardiography
• Fetus is screened to detect any anatomical indicators increasing the risk for chromosomal abnormalities.
• Assessment of the uterus vessel flow to find out whether the placenta is adequately perfused and to assess the possibility of residual endometrial development occurrence or pre-eclampsia requiring more intense monitoring during pregnancy.
3. 3rd Trimester Development Ultrasound
This ultrasound is usually performed at week 32 of pregnancy. Most pregnancies develop normally. However, a low percentage will present implications more frequently in the third trimester including pre-eclampsia, gestational diabetes, delayed endometrial development of the fetus, etc.
• Development screening and measurement of potential fetal weight
• Fetal movement assessment
• Doppler to assess uteroplacental and fetal circulation
• Amniotic fluid quantity assessment
• Assessment of placental appearance and location.
