Effect of the abdominal aortic balloon occlusion applied to caesarean section for pernicious placenta previa and previa accreta / 中国介入影像与治疗学

ABSTRACT

Objective: To investigate the clinical curative effect of the abdominal aortic balloon occlusion in caesarean section for pernicious placenta previa and previa accreta. Methods: Data of 18 puerperants with pernicious placenta previa and previa accreta who underwent the abdominal aortic balloon occlusion in caesarean section were retrospectively analyzed. The amount of intraoperation blood loss and transfusion, the effective rate of balloon occlusion, the occlusion time, hysterectomy and complications were recorded. Results: All the 18 puerperants underwent the abdominal aortic balloon occlusion in caesarean section successly, with the technical success rate was 100% (18/18). The mean amount of blood loss was (1 276.11±761.59)ml during the caesarean section. And the mean amount of leukoreduced red blood cells transfusion was (2.86±1.51)U. No puerperant was dead of bleeding. The effectiveness of the abdominal aortic balloon occlusion was 100% (18/18), with the occlusion time was (24.06±26.19)min. Four (4/18, 22.2%) puerperants were underwent the hysterectomy due to serious placenta implantation, which even extensively invaded the cervix, bladder and intestine. No serious complications related to the abdominal aortic balloon occlusion and the interventional embolization were occured during the caesarean section. Conclusion: For the puerperants with pernicious placenta previa and previa accreta, the abdominal aortic balloon can effectively block blood flow, reduce the amount of blood loss and transfusion during caesarean section, and reduce the rate of hysterectomy and the risk of the operation.
