Placental weight as a trigger for preeclampsia in pregnancies with absent or reversed enddiastolic Doppler waveform alterations

Introduction Placentas of patients with PE share similarities with placentas of cases with severe Doppler waveform alterations like AEDF or REDF of the umbilical artery. The aim of the study was to investigate the incidence of PE in a cases with AREDF to compare placental weight between AREDF cases with or without PE. Material and Methods A ratio between the observed (O) weight the expected (E) mean for GA values (Kaufmann et al) was calculated for all placentas which were included (O/E-ratio). Receiver operating characteristic (ROC) curve was constructed to describe the relationship between sensitivity false-po…
