2. 1st trimester assessment of aneuploidy
• US markers
–
–
–
–
NT, NB, Facial angle
Doppler of DV (a-wave)*
Doppler of tricuspid valve*
Intra-cranial translucency (IT)*
• Biochemical markers
– Fß-hCG and PAPP-A
• Non-invasive prenatal test
(NIPT)
– Decision of invasive test in the
intermediate risk (<1/10-1/1000
followed CFTS)
Dr. To Mai Xuan Hong

4. 1st trimester assessment of aneuploidy
• Oral presentations
– Screening for adverse pregnancy outcomes at 12ws
(Audibert, Francois)
– Combined first trimester biochemistry, NIPT or both?
(Johnson, Jo-An)

applications and limitations (Johnson, Jo-An)

Simon)

5. 1st trimester assessment of growth and Doppler
• Crown-rump length measurement
• Increased Uterine artery Doppler indices (PI
> 90th or 95th centile) associated with
–
Reduced fetal movement
–
Superimposed pre-eclampsia
–
SGA < 10th centile
–
SGA < 3rd centile
–
Still birth
• Low PAPP-A level (<0.3 MoM) or both of
PAPP-A and free ß-hCG (<0.5MoM)
– related to poor placentation (low birth weight and still birth)

7. 2nd trimester assessment
• Ratio of prenasal thickness (PT) and nasal bone length (NBL) (Down
syndrome)
• Fetal facial shape
– Facial height (FH) and facial width (FW) (FH/FW ratio)
– Forehead assessment (Profile line) (Down syndrome)
• Short femur length associated with
– Chromosomal abnormalities
– SGA
– Early preterm delivery
• Increased 2nd trimester uterine artery Doppler indices (> 90th centile)
associated with placental dysfunction)
• Femoral metaphyseal-epiphyseal angle (> 130◦ in achondroplasia)
• Asymptomatic short cervix length is a predictor of intra-amniotic
inflammation

in Europe)
– Decision the best timing of delivery in preterm
pregnancies complicated IUGR
– Surveillance test: CTG, UA and DV Doppler
• Aortic intima-media thickness (aIMT) (> 0.8mm)
– Higher SBP and glomerular dysfuction Hong
