The Clinical Value Of Abdominal Aortic Balloon Occlusion Use In Pernicious Placenta Previa

Objective To explore the feasible treatment plan in the clinical treatment of pernicious placenta previa by studying the outcome of fetomatemal of using prophylactic abdominal aortic balloon occlusion in cesarean section for the patients diagnosed as PPP.Methods In this study,data were analyzed for 116 cases of pernicious placenta previa admitted to our hospital from April 2015 to January 2018.The study group(n = 41)underwent prophylactic abdominal aortic balloon placement before CS and occlusion after delivery.The control group(n = 75)received conventional haemostasis during CS.The primary clinical outcomes were the volume of blood loss during operation,the volume of blood transfusion,operative time,hysterectomy rate,postoperative hospital stay and the outcome of neonatal.Results(1)The volume of intraoperative hemorrhage and volume of blood transfusion in the study group and control group were(947.56 ± 549.31)mL vs(1373.33 ± 884.30)mL,(424.39 ± 565.59)mL vs(843.33 ± 1066.99)mL(P<0.05).(2)In the study group,there were 5 cases of large hemorrhage in or over 2000ml,while in the control group,there were 16 cases of postpartum hemorrhage over 2000ml,and the maximum amount of bleeding was 3700ml.(3)There were no statistical sigficance in the operative time,hysterectomy rate,placenta accrete rate,neonatal weight and asphyxia rate(P>0.05).(4)In patiens with placenta accreta,the study group has 12 cases while control group has 19 cases,the operative time and hysterectomy rate in the two groups were(80.08 ± 16.65)min vs(107.68 ± 22.76)min,(25.0%)vs(68.4%)(P<0.05).Conclusion(1)Prophylactic abdominal aortic balloon occlusion effectively reduces intraoperative blood loss,transfusion,operative time and hysterectomy rate in patients diagnosed as PPP especially in placenta previa with placenta accreta.(2)The patients diagnosed as PPP underwent prophylactic abdominal aortic balloon placement before CS did not increase the adverse pregnancy outcome of neonates,so it is worth popularizing in clinical application.
