    Abstract:
    Rapid accumulation of blood from the placental separation site during cesarean delivery for placenta previa obscures the surgical field and quickly leads to deterioration of the patient's vital signs. We used the following technique in eight cases of intractable bleeding among 49 cesareans for placenta previa. Following failure to control the bleeding by suture at the placental separation site via the lower segment cesarean incision, the vessels were ligated using interrupted 2-3-cm sutures at 1-cm intervals in a circle around the bleeding area on the serosal surface of the uterus. The sutures were placed as deeply as possible in order to reach the endometrium. This led to a marked decrease in bleeding and allowed the small vessels to be easily identified and ligated. The amount of blood transfused and the operation time were gradually reduced as we became adept in the use of this procedure. Our experience suggests that this technique could reduce the use of hysterectomy in cesarean for placenta previa.
