Abstract: Objective To explore the efficacy of prophylactic abdominal aorta arteries balloon occlusion in cesarean section for pernicious placenta previa and placenta increta. Methods A retrospective analysis was conducted in 140 cases of pernicious placenta previa and placenta increta admitted to our hospital during March 2003 and March 2016. The study group(n=111)underwent prophylactic abdominal aorta arteries balloon placement before cesarean section and occlusion after delivery. The control group(n=29)received conventional haemostasis druring cesarean section. The amount of blood loss and blood transfusion during operation, hysterectomy rate, infection rate and neonatal asphyxia rate of the two groups were compared with T test or Chi-square test. Results The volume of intraoperative hemorrhage and volume of intraoperative blood transfusion in the study group and control group were(2 139.19±1 533.748)mL vs(3 968.97±3 103.811)mL,(1 713.06±1 391.495)mL vs(3 237.93±2 461.186)mL,(P=0.004, P=0.003). The hysterectomy rate in the study group and control group was 18.01%(20/111)vs 79.31%(23/29),(P<0.001). There was no statistical difference in the infection rate and neonatal asphyxia rate(P=1.000, P=0.634). Conclusion Prophylactic abdominal aorta arteries balloon occlusion is effective in reducing intraoperative blood loss, transfusion and hysterectomy rate in patients with pernicious placenta previa and placenta increta.
