Abstract
PURPOSE: To evaluate the efficacy of intrauterine inflated Cook Cervical Ripening Balloon (ICRB) in postpartum hemorrhage (PPH) management and fertility preserving for placenta accreta spectrum disorders with placenta previa (previa PAS). METHODS: At a tertiary referral center, 74 patients suffering with previa PAS were entered into this retrospective cohort study from January, 2016 to December, 2020, and were confirmed intraoperatively that abnormal invasive placenta reaches the cervical internal ostium and the upper part of the cervical canal. In control group (n = 39), the combination of infrarenal abdominal aorta balloon occlusion (IAABO) and longitudinal parallel compression suture to lower uterine segment were performed. In study group (n = 35), in addition to the aforementioned surgical techniques, ICRB was implemented at the cervical internal ostium and the outside of the cervix simultaneously. RESULTS: Use of ICRB significantly reduced the rate of peripartum hysterectomy (2.9% vs 30.4%, p = 0.001), and associated with a reduction in surgical time and duration of IAABO (mean 172.7 min vs 206.6 min, p = 0.017; median 30 min vs 40 min, p < 0.001). Use of ICRB significantly reduced the estimated amount of blood loss (median 2500 ml vs 4000 ml, p < 0.001), amounts of packed red blood cells and fresh-frozen plasma transfusion (median 6 U vs 13.5 U, p < 0.001; median 450 ml vs 1200 ml, p < 0.001), postoperative hospital stay and the incidence of oligomenorrhea postoperatively (median 5 days vs 6 days, p = 0.009; 13.8% vs 61.1% p = 0.001). No significant difference was observed between both the groups regarding the use of cryo and PLT, injury of urinary system, relaparotomy, admission to the ICU, postpartum hematocele in uterine cavity, and postoperative complications (including incidence rate of DVT, incidence rate of femoral thrombosis, puerperal morbidity, intrauterine infection, surgical site infection, and deep tissue infection). CONCLUSION: ICRB was a simple, effective procedure for PPH management and fertility preserving in some previa PAS cases in which abnormal invasive placenta reaches the cervical internal ostium and the upper part of the cervical canal, in tandem with IAABO and compression suture.
