Stage	Description	Viability monitoring	Birth
SGA	3rd > EFW/AC < 10th Normal Doppler	Monitor vitality every to 2 weeks	Expectant management Labor induction at 40 weeks
FGR I	EFW/AC < 3rd Normal Doppler	Monitor vitality every to 2 weeks until 34 weeks and every week after 34 weeks	Expectant management Labor induction between 37 and 38 weeks
FGR II	Abnormalities in UA, MCA or CPR	Monitor vitality twice a week	Expectant management Labor induction at 37 weeks
FGR III	Absent-end diastolic in UA	Hospitalization and daily monitoring	Expectant management Birth at 34 weeks by elective cesarean
FGR IV	UA with reversed-end diastolic or DV PI> 95th	Hospitalization and daily monitoring	Delivery when viability (26 – 28 weeks) by elective cesarean section
FGR V	Reversed a-wave DV or frequent FHR decelerations

SGA - small for gestational age; EFW - estimated fetal weight, AC - abdominal circumference; UA - umbilical artery; MCA - medial cerebral artery; CPR - cerebroplacental ratio; PI - pulsatility index; DV - ductus venosus; FHR - fetal heart rate
