ObjectiveTo evaluate the outcomes of uterine-conserving surgery with the occlusion balloon technique followed by uterine or ovarian artery embolization (OAE) in women with placenta accreta.MethodsA total of 31 consecutive patients, who were diagnosed with placenta accreta through grayscale ultrasonography or magnetic resonance imaging prenatally, were retrospectively analyzed in our hospital between October 2015 and September 2017. All of the women underwent a Cesarean section combined with prophylactic placement of a balloon catheter in the abdominal aorta followed by uterine artery embolization (UAE) or OAE when necessary.ResultsTechnical success was achieved in 31 cases (100%), including successful catheterization and inflation of balloons. The uterus was conserved in 30 (96.77%) patients. The estimated blood loss, packed RBC transfused, and the operation time were 1906.45 ± 1117.64 ml, 4(0-6) U, and 88.68 ± 28.35 min, respectively. Out of all of the patients, we found nine cases of bleeding after the release of the balloon. Among these patients, six cases originated from the ovarian arteries and three cases originated from uterine arteries. Further embolization was performed through catheterization. The mean fetal radiation exposure was 4.33 ± 0.79 mGy.ConclusionsProphylactic abdominal aorta balloon occlusion followed by UAE or OAE can effectively control postpartum hemorrhaging with reduced blood loss, transfusion requirements, and hysterectomy rates in patients with placenta accreta.
