Comparative Efficacy of Abdominal Aortic ABO (AABO) vs Common Iliac Artery ABO (CIABO) in Cesarean Delivery for Central Placenta Previa with Placenta Accreta: A Retrospective Study.

OBJECTIVE

To compare the safety and efficacy of abdominal aortic balloon occlusion (AABO) and common iliac artery balloon occlusion (CIABO) in cesarean deliveries for central placenta previa with placenta accreta, using a retrospective study design.

METHODS

We retrospectively analyzed 65 patients with central placenta previa and placenta accreta who underwent cesarean delivery at our hospital between January 2020 and April 2024. Patients were divided into two groups: the observation group (n=35) received AABO, while the control group (n=30) received CIABO. Outcomes compared included intraoperative blood loss, maternal and neonatal outcomes, and other relevant factors. Data were analyzed using SPSS 26.0, with normally distributed quantitative data assessed by t-tests and categorical data by chi-square tests. A p-value <0.05 was considered significant.

RESULTS

The AABO group had significantly reduced balloon placement time, radiation exposure, intraoperative blood loss (mean 800 ± 150 mL vs 1200 ± 180 mL in CIABO; p<0.05), and transfusion volume (mean 400 ± 100 mL vs 600 ± 120 mL in CIABO; p<0.05). The hysterectomy rate was lower in the AABO group (5.7% vs 16.7% in CIABO; p<0.05). No significant differences were observed in postpartum hemorrhage (14.3% vs 13.3%; p>0.05) or neonatal asphyxia (2.9% vs 3.3%; p>0.05). Postoperative coagulation function at 24 hours was better in the AABO group (p<0.05), with no significant difference in postoperative complications (p>0.05).

CONCLUSION

AABO in cesarean deliveries for central placenta previa with placenta accreta reduces intraoperative blood loss and hysterectomy rates without adverse fetal effects, making it a valuable clinical option.
