Maternal-fetal Doppler sonography: potential or reality

Doppler sonography, in its varying forms, has been used by numerous researchers to evaluate the maternal-fetal circulation. Unfortunately, as can be seen from this review, few sweeping conclusions can be drawn from the literature to date. Doppler certainly seems a worthwhile adjunct in the evaluation of patients with any of a number of abnormalities that affect maternal-fetal circulation. Unfortunately, considering the discrepancies in the literature and the recent controversy regarding the use of pulsed and color Doppler in pregnancy, the examination is often avoided. However, there are certainly instances where Doppler can provide unique and valuable information. In these situations, the prudent use of Doppler should be encouraged.
