4Dr. To Mai Xuan Hong
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– 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)
5Dr. To Mai Xuan Hong

hypertension disease of pregnancy (Park, Felicity)

pregnant women(Sahota, Daljit)
– Pulsatility index of the uterine arteries between 11 and 13.6 weeks: comparison
of measurement by transvaginal and transabdominal Doppler ultrasound (Cafici,
Daniel)
– Reduced fetal movement at term association to first trimester uterine artery
Doppler assessment (G Pagani)
– Reduced fetal movement at term: association to first trimester PAPP-A level (G
Pagani)
– Outcomes in cases of low PAPP-A and free ß-hCG in maternal serum at 1st
trimester screening (Deloison)
6Dr. To Mai Xuan Hong
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• 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
