%X Cohort study of singleton pregnancies with risk factors for placental insufficiency, managed at St. Michael's Hospital in Toronto, Canada. Patients undergone UA Doppler assessment at 18-22 weeks' gestation and 6 weeks postpartum. 15 pregnancies complicated by preeclampsia or intrauterine growth restriction (IUGR) (cases) were compared to 17 unaffected pregnancies (controls). Cases with preeclampsia and/or IUGR had higher UA PI at 18-22 weeks than controls. By 6 weeks' postpartum, the corresponding mean values were 2.60 and 2.14 (p = 0.20). This preliminary study suggests a potential different trajectory for physiologic recovery of UA flow after a pregnancy affected by placental insufficiency.
