Delayed postpartum hemorrhage following cesarean section is a rare and life-threatening obstetric complication. Previous reports demonstrated that infection at the uterine incisional wound could unexpectedly lead to active bleeding. We present a case of severe delayed postpartum hemorrhage 28 days after cesarean delivery followed by an abdominal wound inflection. After emergent management such as: intrauterine gauze packing dilatation and cuettage were failed, a subtotal hysterectomy was required to save the patient.
