Several prior studies have demonstrated that the presence of placenta previa protects against the development of preeclampsia. Also, there are no reported cases of eclampsia following cesarean section and hysterectomy. However, we encountered a patient with total placenta previa and accreta who developed severe antepartum preeclampsia followed by the onset of eclamptic seizures after a cesarean section and a subtotal hysterectomy. This case confirms that severe preeclampsia may occur in patients with placenta previa and demonstrate that severe preeclampsia may occur after placental removal and even after subtotal hysterectomy, which removed most of the trophoblastic tissue.
