local.description.resumoObjectives: Physiopathological mechanisms that trigger clinical manifestations in pre-eclampsia (PE) remain unclear, and management is still a challenge. The identification of tools to predict the onset of the disease and prevent its complications is of great interest in medical practice. The present study aims to evaluate uterine perfusion, endothelial function and central nervous system blood flow in pregnant women with high-risk factors for PE, for comparison of the results between the group of patients who developed early onset PE and those who remained normotensive throughout pregnancy.Study design: Sixty-two patients were recruited from our high-risk prenatal service, and followed throughout gestation. Patients were submitted to flow-mediated dilation, Dopplervelocimetry of uterine arteries and Dopplervelocimetry of ophthalmic arteries at three distinct moments of pregnancy: between 16+0 and 19+6 weeks, between 24+0 and 27+6 weeks and at hospital admission to delivery. Main outcome measures: Pulsatility index of uterine arteries, flow-mediated dilation and ophthalmic arteries resistance index were evaluated and compared between the two groups of patients. Results: Ten pregnancies were complicated by early onset PE, and these patients presented a significantly higher pulsatility index of uterine arteries between 16+0 and 19+6 weeks of gestation, compared with the normotensive group (p = 0,016). Both flow-mediated dilation and ophthalmic arteries resistance index values were lower in affected patients at 24+0 to 27+6 weeks (p = 0,001), and by the time of delivery (p < 0,002).Conclusions: Those findings suggest that impaired placental perfusion, endothelial dysfunction and central hy perperfusion temporarily precede the clinical manifestations of early onset pre-eclampsia.
