Abstract
The aim of this study was to evaluate the umbilical and uterine flow velocity wave forms in normal and some pathological pregnancies (pre-eclampia, diabetes and postdate pregnancies), and to assess the correlation between Doppler wave forms and the severity of the maternal disease as well as fetal outcome.
Conclusion:
Doppler velocimetry is a clinically useful, non invasive method of antenatal fetal surveillance. It is less prone to interobserver and intraobserver variation, requires less frequent examination and was less time consuming than other methods of fetal monitoring. It is an earlier and more accurate predictor of chronic fetal hypoxia. It helps in the distinction between small healthy foetus and the one who is truly growth retarded. Another potential use of Doppler ultrasound is fetal surveillance in situations in which electronic fetal monitoring is unreliable, such as pregnancies less than 30 week’s gestation.
Umbilical artery velocimetry is more sensitive and more specific than uterine artery velocimetry and than BPS in predicting chronic fetal hypoxia. The BPS is more sensitive and more specific than the umbilical and uterine artery velocimetry in predicting Apgar score. Both tests (Doppler and BPS) should be considered as complementary tests.
Doppler velocimetry is unlikely to be useful for the routine antenatal assessment of postdate pregnancies.
Clinical studies of uterine artery Doppler velocimetry were contradictory as there have been differences in the techniques of measurements, the indices used to describe an abnormal wave forms, and the out come measures for which the test is predictive.
