The clinical evaluation of preoperative abdominal aortic balloon occlusion for patients with placenta increta or percreta.

OBJECTIVE To evaluate the efficacy and safety of abdominal aortic balloon for pregnant women with placenta increta or percreta (PIP). METHODS Retrospective analysis of the parameters containing estimated blood loss, red cell suspension (RCS) transfusion volume, hysterectomy, surgery time, postoperative hospital days, neonatal status and complications between the two groups. RESULTS The patients with preoperative abdominal aortic balloon occlusion (AABO) had significant reduction in blood loss volume, red cell suspension transfusion volume and plasma transfusion volume compared to patients without balloon. Similarly, the surgery time and hysterectomy were obviously reduced in the AABO group. However, there were no difference in the Apgar scores and neonatal complications between the two groups, indicating that the abdominal aortic balloon has little adverse effect on the newborns. CONCLUSION AABO plays dramatic roles on reducing blood loss volume and blood transfusion volume and it is also a safe and effective technology providing new insight into the therapy of patient with PIP. SYNOPSIS Preoperative abdominal aortic balloon occlusion (AABO), as a new intravascular interventional therapy, is safe and effective in patients with placenta increta or percreta.
