title: Screening for placenta accreta at 11-14 weeks of gestation.
abstract: OBJECTIVE
  We sought to describe the potential value of 11-14 weeks' screening for placenta accreta (PA).
  
  
  METHODS
  Patients with a history of lower segment cesarean section were prospectively included between 11-13+6 weeks over a 1.5-year period. The first 258 were offered standard screening whereas the following 105 underwent screening for PA. Women were considered high-risk when the trophoblast overlapped the scar visualized by transvaginal ultrasound and low-risk otherwise.
  
  
  RESULTS
  The group screened for PA did not differ from the nonscreened group for demographic characteristics. In all, 6 of 105 (5.8%) women were considered high-risk. In the nonscreened group, 1 case of PA was discovered during an elective repeat cesarean. In the screened population, 1 case of PA occurred in a high-risk patient allowing a conservative planned management at 35 weeks.
  
  
  CONCLUSIONS
  At 11-14 weeks, ultrasound may help risk stratification for PA with a specific follow-up. Early recognition of patients at risk might improve the perinatal outcome of PA.
