摘要

CONTEXT:Pregnancies complicated by abruption result in increased frequency of perinatal death and decreased fetal size and gestational duration, yet the extent of placental separation and its effect on these adverse outcomes is unknown.
OBJECTIVE:To assess the contribution of placental abruption and extent of placental separation to stillbirth, preterm delivery, and fetal growth restriction.
DESIGN:Hospital-based, retrospective cohort study.
SETTING:Mount Sinai Hospital, New York City, NY.
PARTICIPANTS:A total of 53,371 pregnancies occurring in 40,789 women who were delivered of singleton births between 1986 and 1996.
MAIN OUTCOME MEASURES:Risks and relative risks for stillbirth (>20 weeks), preterm delivery (
