- Abstract
OBJECTIVE: Establish the reference values for the pulsatility index using pulsed Doppler in the maternal and fetal assessment of pregnancies followed at 18 and 39 weeks of gestation. MATERIALS AND METHODS: Descriptive and cross-sectional study, carried out in patients with a singleton pregnancy, between 18 and 40 weeks, who attended the Department of Maternal Fetal Medicine of the National Institute of Perinatology, from September 2017 to May 2018. The Doppler evaluation was performed, with measurement of the pulsatility index of the uterine, umbilical, middle cerebral arteries, and venous duct in each week of pregnancy. Reference tables were created for each gestational age, establishing percentiles 3, 5, 10, 90 and 95. RESULTS: A total of 862 patients were registered. The umbilical artery pulsatility index values were reported to be 17% at early gestational ages and 21% at older gestational ages; Umbilical artery values were 3% lower at early gestational ages and 10% lower at term of pregnancy; 20% for the umbilical artery, 15% for the ductus venosus and 10% for the middle cerebral artery. The values of the mean pulsatility index of the uterine arteries were 3% higher at early gestational ages and 28% lower at the end of pregnancy. CONCLUSIONS: The findings of this study suggest significant differences with the populations of Europe and North America; They even differ from the reference values currently used in the Mexican population, which represents an underestimation of fetal and/or maternal conditions when carrying out evaluations of the feto-placental unit.
