Role Of Prophylactic Abdominal Aorta Balloon Occlusion In The Management Of Women With Complete Placenta Previa

Objective.To evaluate the effectiveness and safety of prophylactic balloon occlusion of the abdominal aorta in women with complete placenta previa.Methods.Retrospective case-control study of women diagnosed with complete placenta previa at the People’s Hospital of Guangxi Zhuang Autonomous Region from march 2013 to march 2016. Cases were divided into two groups.Fifty-eight cases was underwent prophylactic temporary balloon occlusion(BC),followed by cesarean section.Eighty-eight cases was underwent cesarean alone.Statistical analysis were considered:estimated blood loss, transfused blood products units, operative time, incidence of postpartum heamorrhage, cesarean hysterectomy rate, Apgar score at 1 and 5 min and hospital length of stay. Surgical complications, balloon catheter-related complications, and fluoroscopy times were also reported.Results.Mean estimated blood loss and transfused blood products units were lower in the BC group compared with group cesarean alone(878.45ml vs 1680.68 m\,P=0.002; 1.36 units vs 3.39units,P=0.028).Mean operative time were also shorter in the BC group than the group cesarean alone(81.02 minutes vs 101.56minutes,P=0.029).And the incidence of postpartum heamorrhage were lower for the group that had BC compared with the group that did not too(25.9% vs 46.6%,P=0.012).No difference in cesarean hysterectomy rate, Apgar score at 1 and 5 min and hospital length of stay were found between the BC plus cesarean and the cesarean alone groups.There were no major catheterization-related complications.Conclusion.During scheduled caesarean section for complete placenta previa,Prophylactic balloon occlusion of the abdominal aorta is a effectiveness and safety treatment.Prophylactic balloon occlusion of the abdominal aorta can reduce intraoperative blood loss,shorter operative time and reduce the risk of postpartum heamorrhage.
