DOPPLER ANALYSIS IN PREGNANCIES COMPLICATED BY PREGNANCY-INDUCED HYPERTENSION AND FETAL GROWTH-RETARDATION

Pregnancy-induced hypertension (PIH) is a relatively common complication of pregnancy. In the present study we evaluated the role of Doppler ultrasound in the management of 36 patients with the disorder. Ultrasound assessment of amiotic fluid was performed on alternate days until parturition, as well as weekly ultrasound measurement of fetal abdominal circumference. Doppler analysis of maternal/fetal circulation was performed on alternate days until delivery. The Doppler indices were not revealed to the labor staff and were correlated with pregnancy outcome. Obstetric management was decided by the attending obstetricians by interpreting echographic features. fetal heart rate tracings, and/or deterioration of maternal condition. Our data show that in severe PIH, growth-retarded fetuses with absent or reversed diastolic flow in the umbilical artery are at higher risk for earlier delivery, decreased birth-weight, increased neonatal suffering. and perinatal mortality than those with flow throughout diastole.
