Placenta previa with focal accretion.

A series of eight women in whom a diagnosis of placenta previa with focal accretion was established, is presented. They were selected from a group of 153 women with placenta previa who delivered during the period 1968-77. The women with placenta previa accreta did not differ from those with placenta previa per se with respect to age, parity, obstetrical history, and antenatal, intrapartum or perinatal outcome. Three women delivered vaginally and five by cesarean section. Postpartum hemorrhage occurred in four of the women, three of whom were delivered vaginally. Of seven women who were managed conservatively, one required a hysterectomy to control bleeding. It is suggested that cases of placenta previa with focal accretion be managed conservatively.
