Lesson Progress
0% Complete

The most common cause of FGR is placental disease, which tends to have two main clinical manifestations
– early and late

  • Early onset FGR is often associated with reduced villous cross-sectional vascular area of the placenta which results in a perfusion defect and elevated umbilical artery (UA) blood flow resistance. This type of FGR typically develops in mid-trimester and presents with an SGA fetus and abnormal UA Doppler 8
  • Late onset FGR is more common than early onset disease, usually develops after 32 weeks and is associated with villous immaturity and other pathologies producing a placental diffusion defect where reduction in villous cross-sectional area is often below the threshold detectable by UA Doppler 9.
