Pregnancy management after diagnosis of type 1 sFGR

sFGR: selective fetal growth restriction; UA: umbilical artery; MCA: middle cerebral artery; BPP: biophysical profile (including nonstress test); DV: ductus venosus; PI: pulsatility index.
* Doppler results indicating worsening disease warranting more frequent fetal surveillance include UA PI >95^th percentile, MCA PI <5^th percentile, or progression to type 2 or 3 sFGR.
