Uterine artery Doppler flow studies in obstetric practice.

In women who develop preeclampsia there is a pathological increase in placental vascular resistance should be detectable by abnormal Dopplerf low studies of the maternal uterine vessels. In women considered at low risk with abnormal early pregnancy uterine artery Doppler studies are needed. Until such time as these are available, routine uterine artery Doppler screening of women considered at low risk is not recommended. Uterine artery Doppler screening of high-risk women appears to identify those at substantially increased risk for adverse pregnancy outcomes and interventions that might improve clinical outcomes.Abnormal testing in these women could potentially lead to increased surveillance and interventions that might improve clinical outcomes.
