Comparison of perinatal outcome in fetuses with reverse or absent enddiastolic flow in the umbilical artery and/or fetal descending aorta

Abstract

The present study suggests that reversed flow should be seen as a particular clinical entity with higher incidences of perinatal and overall mortality, and severe intrauterine growth retardation (< 5. perc) compared to the absent enddiastolic flow group. The optimal timing of delivery in pregnancies complicated by highly pathological Doppler flow findings is only to be resolved in well-designed randomized, multicenter clinical trials.
