4.8 Risk assessment (2/2)

  • Previous small for gestation age (SGA), if determined by customised centiles, is more likely to be due to fetal growth restriction (FGR) than if SGA is determined by population centiles. It is therefore more likely to represent increased risk and is often the only available indicator of the likelihood that there was indeed previous FGR. 
  • Obstetric review should consider severity, gestational age at onset (if known), gestational age at delivery and associated factors such as preeclampsia.
  • Previous stillbirth is considered an increased risk, regardless of size and stated cause, unless placental insufficiency has been excluded by placental pathology examination
  • For women with a history of, or significant risk factor for, placental dysfunction (including history of pre-eclampsia or fetal growth restriction), Aspirin 75-150mg nocte is recommended from 12 weeks to birth according to the latest NICE guidelines 38
