Clinical analysis of 16 cases of placenta accreta

Objective: To discuss the etiology,diagnosis and treatment of placenta accreta.Methods: Sixteen placenta accreta cases were analyzed retrospectively and the relative literature was reviewed.Seven of the sixteen cases received emergency hysterectomy,four cases were treated with sature and compression hemostasis,one case was performed intrauterine pack with gauze for hemostasis,three cases received uterine artery perfusion plus embolism treatment and one case failed in conservative treatment.Results: Of the 4802 delivery cases,placenta accreta occurred in 16 cases,with an incidence rate of 1:300.Among the 16 cases,placenta previa was observed in 10 cases and previous cesarean delivery in 4 cases;4 cases were found to have more than 3 times of induced abortion and 11 cases had 2 times of induced abortion.No one died.Conclusions: The related risk factors include placenta previa,previous cesarean delivery and multiple induced abortion.Early prenatal diagnosis of placenta accreta is important for the prognosis of the disease.Emergency hysterectomy is usually inevitable for cases with serious hemorrhage;conservative treatment is usually adopted to cases of non-emergency and women with the desire of procreation.
