Objectives: To analyze the role of middle cerebral artery (MCA) peak systolic velocity (PSV) in the prediction of severe fetomaternal hemorrhage (FMH) and to compare it with standard biophysical assessment. Data Sources: Retrospective review of cases of FMH seen in our unit and systematic review of the literature. Results: We followed the MOOSE guidelines to review the literature. From 838 articles, 16 were selected. In total, 35 women, including 3 cases from our center and 32 obtained from the literature search were included. Diagnosis of FMH was always confirmed by laboratory tests. Patients were seen at 31 ± 5 weeks' gestation (range 16-39) and the most frequent indication for referral was decreased perception of fetal movements. Cardiotocography (CTG) upon admission was sinusoidal in 18 cases, nonreactive in 6, decelerative in 2 and tachycardic in one. MCA-PSV was abnormal in all cases but one. There were 2 perinatal deaths. The mean hemoglobin concentration at birth or at intrauterine transfusion was 4.8 ± 1.9 g/dl. Discussion: The most accurate predictor of FMH was fetal MCA-PSV. CTG was always abnormal but the pattern was frequently nonspecific. We suggest including fetal cerebral Doppler in the evaluation of patients with decreased fetal movements, particularly in those cases with ambiguous results of biophysical testing.
