Clinical curative effect of balloon occlusion of distal abdominal aorta in cesarean section for patients with pernicious placenta previa and placenta accreta / 中国介入影像与治疗学

ABSTRACT

Objective To analyze the clinical efficacy of balloon occlusion of distal abdominal aorta for patients with pernicious placenta previa and placenta accreta.Methods Data of 72 patients with pernicious placenta previa and placenta accreta were retrospectively analyzed.There were 53 cases (occlusion group) reserved balloon occlusion in abdominal aorta before cesarean section,which can temporarily blocked abdominal aortic blood flow during operation.The other 19 cases (non-occlusion group) underwent cesarean section without balloon occlusion of abdominal aorta.The intraoperative,post operative situations and the birth state of newborn of the two groups were compared.Results The bleeding,blood transfusion and hysterectomy rate during the operation in occlusion group were less than those in non-occlusion group (all P＜ 0.05).Differences of the rate of postoperative transferring to intensive care unit (ICU) and the time in ICU were statistically significant between two groups (both P ＜0.05).No statistical difference of operation time,postoperative total hospital stay time and the rate of postoperative infection was found between two groups (both P＞0.05).There was no statistical difference of newborns weight and Apgar scores (5 min and 10 min after birth) between two groups (all P＞0.05).Conclusion The balloon occlusion of distal abdominal aorta in cesarean section for patients with pernicious placenta previa and placenta accreta is safe and feasible,which can effectively reduce the intraoperative bleeding,the blood transfusion and the risk of hysterectomy.
