Avoidance of Death Handicap
  • Fetal abnormalities
  • Impaired placentation
  • Preterm delivery
  • Kypros Nicolaides 2006

The 11-136 weeks scan
  • Increased NT is associated with
  • All major chromosomal abnormalities
  • More than 50 defects genetic syndromes
  • The risk increases with NT thickness

Successful examination of fetal anatomy at
11-136 weeks
Transabdominal and / or transvaginal scan

The 18-23 week scan
  • Fetal biometry
  • Fetal anatomy
  • Fetal activity
  • Placental localisation
  • Amniotic fluid volume

  • Screening for trisomy 21 by NT, fß-hCG PAPP-A
    can detect 90 of other chromosomal defects
  • Each chromosomal defect has its own syndromal
    pattern of sonographic and biochemical markers
