Abstract
notch and clinical risk factors were present in 41.9% and 11% of women respectively. There were statistically significant differences between Doppler indices from pregnancies with or without subsequent PE or associated complications: mean PI 1.75 vs 2.04 (P = 0.002, t-Student test) and mean RI 0.75 vs 0.79 (P = 0.000, t-Student test). A multivariate logistic regression produced a two parameter model (including the mean PI and the presence of clinical risk factors) with the best sensitivity (46.27%) and specificity (80.99%) for the prediction of PE and its associated complications. Conclusion: There are differences in uterine Doppler blood flow indices at 11–14 weeks in pregnancies with or without subsequent PE and /or associated complications. The combination of mean PI with the presence of clinical risk factors at this gestational age show the best sensitivity and specificity for the prediction of PE and its associated complications in our population.
