Abstract: Objective To compare the safety and effectiveness of temporary occlusion techniques with different balloons in performing cesarean section for patients with pernicious placenta previa.Methods The clinical data of 15 patients with pernicious placenta previa,who received cesarean section during the period from March 2014 to April 2016,were retrospectively analyzed.In order to reduce bleeding during operation and to preserve the uterus as far as possible,temporary occlusion of abdominal aorta with balloon was adopted in 7 patients (group A),and temporary balloon occlusion of bilateral internal iliac arteries was employed in 8 patients (group B).The intraoperative radiation dose,the amount of blood loss and blood transfusion during cesarean section,the hysterectomy rate,the postoperative hospitalization days,and the intervention-related complications were documented,and the results were compared between the two groups.Results All the 15 patients were suffered from central type of placenta praevia complicated by extensive placenta accreta.With the help of temporary balloon occlusion technique,the cesarean section was successfully accomplished in all 15 patients.Subtotal hysterectomy had to be done in 7 patients,including 4 patients of group A and 3 patients of group B,and every one patient from each group developed arterial thrombosis of lower limb.The intraoperative radiation dose of group A was significantly lower than that of group B (P＜0.01),besides the amount of blood loss and blood transfusion during cesarean section,the hysterectomy rate,the postoperative hospitalization days,and the intervention-related complications of group A were all lower than those of group B,but because of the limited number of cases these differences were not statistically significant (P＞0.05).Conclusion For the treatment of pernicious placenta previa,temporary balloon occlusion technique-assisted cesarean section is safe and effective.The intraoperative radiation dose in the group using temporary balloon occlusion of abdominal aorta is remarkably lower than that in the group using temporary balloon occlusion of bilateral internal iliac arteries.
