Are maternal and neonatal outcomes different in placental abruption between women with and without preeclampsia?

abstract：INTRODUCTION:Chronic abruption oligohydramnios sequence (CAOS) is histologically characterized by diffuse chorioamniotic hemosiderosis (DCH). However, the criteria for the histological evaluation of the extent of CAOS-related hemosiderin deposition (HD) of the membranes and the difference in HD between the chorionic pl...
