Methods: A prospective matched control multicentric study of 220 IUGR fetuses (abdominal circumference <5th percentile; increased umbilical artery pulsatility index). Among these, 110 fetuses were IUGR from normotensive women and 110 associated to maternal preeclampsia. Doppler velocimetry of UA, MCA, DV, evaluation of amniotic fluid index was performed twice weekly and cardiotocography and BPS daily. Delivery was performed <32 weeks if there were signs of fetal compromise (BPS <4 or cardiotocographic alterations), or maternal indications for preeclampsia. Perinatal mortality and composite morbidity (5 min. Apgar, RDS, BPD, ROP, IVH, PVL, and NEC) was recorded and correlated with Doppler parameters. Results: Among 220 IUGR fetuses, in IUGR fetuses of normotensive mothers mean gestational age at delivery was 29.3 °æ 1.8 weeks, and mean birth weight was 939.7 °æ 164.9gr. In IUGR fetuses associated to maternal preeclampsia mean gestational age was 28.8 °æ 2 weeks, and mean weight at birth 878.9 °æ 262.4 gr. The temporal sequence of IUGR fetuses associated to preeclampsia show an earlier onset of Doppler alterations compared to IUGR fetuses of normotensive mothers. Considering neonatal outcome, in IUGR fetuses of normotensive mothers the morbidity, mortality and fetal death was higher compared to IUGR from preeclamptic women. Conclusions: The present study highlights that IUGR fetuses should be divided into two entities: isolated IUGR due to placental vascular insufficiency and IUGR fetuses associated to maternal preeclampsia. This distinction is essential to manage these fetuses since IUGR fetuses without maternal preeclampsia develop cardiovascular compromise in a longer period of time compared to IUGR fetuses from preeclamptic women.
