Fetal and maternal platelet counts were correlated with antenatal assessment of the umbilical-placental waveform. Forty singleton pregnancies were studied using Doppler ultrasound, and placental resistance was categorized as normal or high according to the systolic/diastolic ratio. We performed platelet counts on maternal and cord blood taken at the time of cesarean section. The high-resistance group had a mean fetal platelet count (218 ± 53 × 103/μL significantly lower than that of the normal-resistance group (314 ± 76 × 103/μL) (P<.001). This difference was evident in both the hypertensive and nonhypertensive subgroups of, the high-resistance group. There was no difference in mean maternal platelet counts between the high- and normal-resistance groups.
