Materials and Methods: The clinical records of 37 patients with pernicious preplacental placenta were retrospectively analyzed. Sixteen patients who underwent cesarean section postoperative uterine artery embolization (UAE) were classified into group A, while 21 patients who received preset femoral catheterization followed with immediate UAE after the fetus was delivered by cesarean section were classified into group B. The therapeutic effects were compared. Results: The average amount of blood loss and infusion of patients in groups A and in B was 2,621 ± 626 ml and 6.23 ± 2.66 U and 1455 ± 486 ml and 3.03 ± 2.12 U, respectively (p < 0.01). One patient of group A received hysterectomy and no hysterectomy was seen in patients of group B. Conclusion: Intraoperative UAE using preset femoral artery catheterization prior to cesarean section has effectively reduced blood loss and infusion.
