Study objective: Evaluate whether ductus venosus (DV) Doppler velocimetry might be a good diagnostic tool of neonatal acidosis than umbilical artery (UA) and middle cerebral artery (MCA) blood velocities.Design: Prospective observational study.Setting: High risk pregnancy unit of Ain Shams University Maternity Hospital.Patients: Thirty high-risk pregnant patients in their third trimester.Method: Recording of DV, UA and MCA blood velocity in complicated pregnancies referred to umbilical artery (UA) velocimetry as one aspect of fetal surveillance.Measurements and main results: DV S/D ratio was not reliable to predict hypoxia (AUC 66%), PI was weak (73%), but RI was reliable to predict hypoxia (AUC 88%). On comparing the diagnostic ability of DV RI and MCA S/D, DV RI showed a diagnostic ability than MCA S/D, AUC 88% and 82% respectively.Conclusion: Abnormal DV blood velocity is more frequently recorded in high-risk pregnancies than UA, MCA blood velocities. Ductus venosus resistance index (DV RI) appears to be a better predictor of perinatal outcome than MCA S/D
