Uterine artery resistance is assessed to detect inadequate placentation in pregnant women, that increases the risk to develop preeclampsia, intrauterine growth restriction and other complications associated with placental insufficiency. Objective: To identify the uterine arteries pulsatility index (UtAPI) reference chart that best fits our institutional data. Methods: Retrospective, cross-sectional study that evaluated 1 753 single pregnancies; 2 031 UtAPI measurements of the uterine arteries were obtained. Mean UtAPI was compared with the reference charts published by Gomez, Limay and Weichert. Results: There was a mild but significant (r=0.16) negative correlation between UtAPI and gestational age between 24 and 40 weeks of gestation; 6.5%, 7.5% and 15% of our measurements were above the 95 centile of respectively Weichert, Limay and Gomez reference charts. Conclusions: In our population, the UtAPI distribution fitted best with Weichert reference chart. More prospective studies are needed to validate this clinical finding.
