“…The PE diagnosis was based on the clinical classification of the disease in mild and severe forms 15 and the classification based on the beginning of clinical manifestations, i.e. early PE (patients with onset of symptoms before 34 gestational weeks) and late PE (patients in which symptoms begin after 34 gestational weeks).…”

Introduction: Hypertensive disorders represent the most frequent and serious complications of pregnancy and childbirth. Abnormal findings upon uterine artery Doppler, including altered values of pulsatility index and average persistence of bilateral diastolic notch, have been proposed as suitable predictors of preeclampsia in screening tests. Objectives: To evaluate the usefulness of uterine artery Doppler in predicting the occurrence of preeclampsia in a group of women at clinical and epidemiological risk for its development. Patients and methods: 81 pregnant women, all of which with risk factors for developing preeclampsia were selected. The average pulsatility index exams were performed on gestational intervals of 16+0 and 19+6 weeks and 24+0 and 27+6 weeks. In the latter range, the persistence of bilateral diastolic notch was also assessed. Results: Bilateral diastolic notch between 24+0 and 27+6 weeks of gestation could predict the diagnosis of preeclampsia with 75% sensitivity, 82% specificity, positive predictive value of 50% and negative predictive value of 93%. The analysis of data obtained between 16+0 and 19+6 weeks and between 24+0 and 27+6 weeks demonstrated that high values of mean pulsatility index were found in patients affected by preeclampsia compared with those found in the group of normotensive patients. Conclusion: pregnancies complicated by preeclampsia had significantly higher prevalence of bilateral notches and higher mean pulsatility indexes in each of the ranges studied. Since no specific treatment is currently available, the ability to predict the disease at its onset, in the first half of pregnancy, can facilitate early monitoring, increased support, and the ability to intervene at the appropriate time so as to reduce the maternal-fetal morbidity and mortality observed in preeclampsia.
