Placenta accreta spectrum is frequently managed with cesarean hysterectomy, but conservative approaches are emerging. We present a case of delayed postpartum hemorrhage secondary to a retained placenta increta.Case: A 29-year-old G3P2 presented with heavy vaginal bleeding 20 days postoperatively following an uncomplicated classical cesarean delivery at 27 5/7 weeks’ gestation for preterm labor in the setting of a vasa previa. On workup, imaging showed retained products of conception and concern for placenta accreta. A hypervascular area in the lower uterine segment was identified at the time of postpartum laparotomy. Total abdominal hysterectomy was performed due to postpartum hemorrhage and clinical suspicion for placenta accreta spectrum disorder. Pathology confirmed a placenta increta.Conclusion: Diagnosis of placenta accreta spectrum in the remote postpartum period is uncommon but should be a considered etiology in delayed postpartum hemorrhage. Careful inspection and documentation of the placenta implantation site should occur in cesarean sections because placenta accreta spectrum disorders can remain unnoticed during delivery.Keywords: delayed postpartum hemorrhage, placenta accreta, pregnancy, hysterectomy, vasa previa
