ObjectiveTo explore the application value of the internal iliac artery balloon occlusion in cesarean section patients with pernicious placenta previa (PPP).

MethodsThe clinical data of 86 puerperas were retrospectively analyzed.Fifty cases treated with internal iliac artery balloon occlusion and 36 cases treated with cesarean section were divided into the balloon group and control group, respectively.The operative time, intraoperative blood loss, intraoperative blood transfusion, hysterectomy rate, postoperative hospital stay and related complications were compared between two groups.

ResultsThe intraoperative blood loss and intraoperative red blood cell transfusion in balloon group (1 585.3±769.9)mL, (4.5±3.8)U were less than those in control group (2 044.1±1 362.9)mL, (6.8±4.9)U, respectively (P < 0.05).The hysterectomy rate and bladder injury rate in balloon group and control group were (40.00%, 12.00%) and (44.44%, 11.11%), respectively, and the difference of which was not statistically significant (P>0.05).One case of right lower extremity artery thrombosis occurred in balloon group.

ConclusionsThe internal iliac artery balloon occlusion in cesarean section patients with PPP can reduce the amount of intraoperative blood loss and blood transfusion, but not effectively reduce the rate of uterine resection, and has a risk of occuring thrombus.
