Dynamic of abnormal uterine perfusion during pregnancy and perinatal outcome

Objective: Abnormal uterine perfusion in second trimester is a risk indicator regarding preeclampsia and IUGR. During ongoing pregnancy uterine perfusion often improves or even normalizes. This study analyses how far perinatal outcome is influenced by this dynamic. Methods: 137 second trimester pregnancies (week 18 to 26) were included in this retrospective study. All patients were characterized by an abnormal uterine perfusion (mean pulsatility index of both uterine arteries >1.4 and/or bilateral notching). A second doppler examination was performed 4 weeks later and/or following clinical necessity. Results: 35…
