ObjectivesTo evaluate the efficacy of prophylactic balloon occlusion (PBO), and to compare haemostatic effects and perioperative outcomes of PBO of the internal iliac arteries (IIA), common iliac arteries (CIA) and infrarenal abdominal aorta (IAA) in patients with placenta accreta.MethodsOne hundred and ninety-nine patients with placenta accreta were retrospectively reviewed. One hundred and twelve cases who underwent PBO were allocated into PBO group, and 87 cases without endovascular intervention were classified as the control group. According to different methods, 112 patients in the PBO group were divided into IIA (n = 37), CIA (n = 42) and IAA (n = 33) subgroups.ResultsPatients in the PBO group had decreased estimated blood loss (EBL) and blood transfusion volume (BTV), as well as improved other perioperative outcomes. PBO (vs controls) could independently predict less EBL. As to comparison among subgroups, patients had decreased EBL and BTV, as well as improved other perioperative outcomes in CIA and IAA subgroups compared to the IIA subgroup. Further validation by multivariate analysis revealed that PBO of IIA (vs others) could independently predict more EBL.ConclusionsPBO reduces intraoperative blood loss and improves other perioperative outcomes in patients with placenta accreta, and PBO of the CIA and IAA is more effective compared to PBO of IIA.Key Points center dot PBO of IIA, CIA and IAA is effective in placenta accreta.center dot PBO of CIA and IAA is more effective.center dot PBO could independently predict less EBL.center dot Accreta depth was an independent risk factor for EBL.
