PurposeTo investigate safety and efficacy of intra-aortic balloon occlusion (IABO) versus internal iliac artery balloon occlusion (IIABO) for cesarean delivery in coexisting placenta accreta and placenta previa.Materials And MethodsFrom 2006 to 2019, 60 pregnant women who had undergone preoperative IABO (n = 28) and IIABO (n = 32) for cesarean delivery in coexisting placenta accreta and placenta previa were retrospectively identified, and their medical records and relevant imaging were reviewed.ResultsMaternal characteristics (age, gravidity, previous cesarean delivery, gestational age, and neonatal weight) were similar in both groups. Estimated blood loss, volume of blood transfusion, length of hospitalization, and rate of hysterectomy were not significantly different between the groups. Operation time (the duration of cesarean delivery and hysterectomy, p < 0.05), total time of balloon occlusion (p < 0.01), and fetal radiation dose (p < 0.001) in the IABO group were less than in the IIABO group. No severe complications related to the balloon occlusion procedure were noted in either group.ConclusionIABO and IIABO are safe and effective options for cesarean delivery in patients with combined placenta accreta and placenta previa. The average operation time, balloon occlusion time, and fetal radiation dose in patients with IABO are less than in patients with IIABO. There were no complications related to balloon occlusion of the aorta or internal iliac artery.
