Pregnancy outcome. <jats:italic>Results.<\/jats:italic> UtARI did not vary significantly between the three groups (0.73, 0.70 and 0.71, respectively). Women in Group 1 had a significantly higher prevalence of uterine artery notching than those in Group 2 (73 vs 57%, <jats:italic>p<\/jats:italic> = 0.04). In Group 1, the UtARI and prevalence of notching was not significantly increased when pregnancies were subsequently complicated by pre\u2010eclampsia (<jats:italic>p<\/jats:italic> = 0.60 and 0.61, respectively). However, in 12 pregnancies requiring delivery before 37 weeks due to pre\u2010eclampsia, fetal growth restriction, abruption or intrauterine fetal death, the UtARI was significantly higher than in the 44 pregnancies with normal outcome (<jats:italic>p<\/jats:italic> = 0.04). A combination of UtARI and notching showed sensitivities up to 75% and negative predictive values up to 88% for adverse outcome before 37 weeks. <jats:italic>Conclusions.<\/jats:italic> In pregnancies following a previous gestation complicated by pre\u2010eclampsia, first trimester uterine artery Doppler findings are similar to those observed in nulliparous women. In these high\u2010risk women, a combination of UtARI and notching can predict the risk of adverse outcome before 37 weeks.<\/jats:p>","DOI":"10.1080\/00016340802460347","type":"journal-article","created":{"date-parts":[[2008,10,24]],"date-time":"2008-10-24T12:02:08Z","timestamp":1224849728000},"page":"1271-1275","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["First
