Abstract Aim: The aim of this prospective study was to
assess the role of uterine artery color Doppler waveform
analysis in the prediction of adverse pregnancy outcome
such as preeclampsia, intrauterine growth retardation,
placental abruption or a combination of outcome parameters
in risk pregnancies (n=52). Methods: Various
uterine artery Doppler ultrasound parameters (resistance
index (RI)0.58, RI0.7 and uni/bilateral or bilateral
notching) were tested. The mean time of delivery was 37
+1 weeks’ gestation. Six newborns (12%) were delivered
before 34 weeks of gestation. The mean birth weight was
2,910 g. Dystrophic fetuses (10% percentile) were
registered in 7 cases (13%). In 11 of the 52 women
(21%) a cesarean section was performed because of
abnormal fetal heart recording. Results: Preeclampsia
was diagnosed in 4 cases (8%). In 4 cases (8%) an
intrauterine fetal death was diagnosed. Placental abruption
did not occur. The sensitivity of notching for the
prediction of preeclampsia and for the prediction of a
severe pregnancy complication was 75 and 69% with
relative risks of 2.7 and 2.0. The sensitivity of notching in
the uterine arteries for developing an intrauterine growth
retardation (IUGR) was 71% with a relative risk of 2.2.
The sensitivity of RI0.58 in the uterine arteries for
developing an IUGR was 67% with a relative risk of 5.4.
The sensitivity of RI0.58 for the prediction of preeclampsia,
of intrauterine death and for the prediction of a
severe pregnancy complication was 50, 75 and 80% with
relative risks of 2.7, 8.1 and 10.9 respectively.
Conclusion The results of this study suggest that Doppler
ultrasound of the uterine artery in the second trimes
