The pulsatility index of the uterine artery can be used to estimate the risk of preeclampsia. In the second and third trimesters of pregnancy. Objective: To generate knowledge about the pulsatility index of the uterine arteries in the prediction of preeclampsia in pregnant women between 11 and 14 weeks. Materials and methods: It is a descriptive study of literature search and has been carried out in Pubmed, Medline, Scielo, libraries of national and international universities. Results: The average pulsatility index in pregnant women with pre-eclampsia was varied ranging from 1.92 to 2.41, having as cut-off points of IP> 1.71 (p <0.05), in the color doppler of the uterine artery at 1114 weeks gestation. The association of pre-eclampsia according to the pulsatility index of the uterine artery between 11 and 14 weeks, is a good method for screening women at risk of developing preeclampsia, since it has a varied sensitivity, specificity, PPV and NPV, but enough to accept it as a predictive method of pre-eclampsia. Conclusions: There is sufficient evidence to conclude that the use of the pulsatility index by Doppler ultrasound of the uterine artery is a suitable method for detection at 11 to 14 weeks gestation in women to develop pre-eclampsia.
