ObjectiveTo evaluate pre-cesarean prophylactic balloon placement (PBP) in the internal iliac artery among women with pernicious placenta previa.MethodsThe present retrospective study included women with pernicious placenta previa who underwent cesarean delivery at Shanghai Renji Hospital, Shanghai, China, between March 1, 2011, and June 30, 2017. Data were compared between patients who did and did not undergo PBP.ResultsAmong 42 patients included, 20 underwent PBP and 22 did not. Mean ± SD estimated blood loss was 2900.00 ± 2352.21 mL in the PBP group, and 4549.77 ± 2366.67 mL in the non-PBP group (P=0.025). The amount of transfused red blood cells was 8.40 ± 7.14 U and 13.00 ± 7.93 U (P=0.018), respectively. No patients in the PBP group developed postoperative disseminated intravascular coagulopathy, compared with 3 (14%) in the non-PBP group (P=0.087). In the PBP and non-PBP groups, the hospital stay duration was 7.40 ± 3.07 and 8.68 ± 2.58 days (P=0.029), and there were 1 and 7 patients who had obstetric hysterectomies (P=0.027), respectively. Two patients experienced PBP-related adverse events, including thrombosis and re-bleeding. There were no deaths.ConclusionPre-cesarean PBP in the internal iliac artery was a safe and effective treatment that could reduce the incidence of both postpartum hemorrhage and hysterectomy among women with pernicious placenta previa.© 2018 International Federation of Gynecology and Obstetrics.
