Evidence-based approach to umbilical artery Doppler fetal surveillance in high-risk pregnancies: an update.
Antepartum fetal surveillance with Doppler ultrasound of umbilical artery has shown significant diagnostic efficacy in identifying fetal compromise in pregnancies complicated with fetal growth restriction and preeclampsia. Moreover, randomized clinical trials and their meta-analyses have shown its effectiveness in decreasing perinatal mortality (level I evidence). This is the only antepartum fetal test that has shown this level of effectiveness. There is no evidence that routine Doppler in low-risk pregnancies improves the outcome. It is recommended that umbilical artery Doppler should be the standard of practice in managing high-risk pregnancies complicated with fetal growth restriction and preeclampsia (level A recommendation). However, its use should be integrated with other current fetal monitoring tests (levels B and C recommendation). The overall management should also be guided by additional clinical considerations such as the gestational age, fetal and maternal status, and obstetrical conditions.
