Autologous blood transfusion for the patient with placenta previa complicated by placenta increta: a case report.

The patient, who was 34 years of age, had previously had a transverse incision of the lower uterine segment cesarean section because of placenta previa. She was admitted to the hospital due to placenta previa again at 27 weeks of gestation in the current pregnancy. Ultrasound examination revealed placenta increta as well as placenta previa. In an attempt to avoid homologous blood transfusion at the time of profuse hemorrhage anticipated to occur during cesarean section, an autologous blood transfusion was planned. Fifteen hundred ml of autologous blood was collected by a leap-frog method during the 8 weeks prior to cesarean section. A cesarean hysterectomy was performed at 37 weeks of gestation because of placenta increta. Blood loss was estimated at 1,830 ml, and 1,500 ml of autologous blood was transfused. A leap-frog method of autologous blood collection for this pregnant woman with risk of massive hemorrhage was simple and beneficial, resulting in the preservation of more than 1,500 ml of autologous blood for transfusion.
