Abstract
Early detection of preeclampsia remains a challenge to the health system to reduce maternal and neonatal mortality rates. Using the mean uterine artery pulsatility index (MeanUAPI) with other maternal markers could contribute to comprehensive care during pregnancy. We performed a cross-sectional study in 579 women to evaluate if there is a difference in MeanUAPI values using two different insonation routes by pulsed Doppler transabdominal (TA) and transvaginal (TV) in patients without risk factors between 11-13 + 6 weeks of pregnancy in two cities located in highlands of Ecuador. The average age was 29 years. A total of 376 (65%) patients were evaluated via TA with a MeanUAPI of 1.61 points. While 203 (35%) were evaluated via TV with a MeanUAPI of 1.57 points, the statistical test did not find a statistically significant difference between the two ways (p=0.406). Therefore, any route could be used to predict preeclampsia with this method during this period.
