Application of intraoperative abdominal aortic balloon occlusion for bleeding during cesarean section in pernicious placenta previa.

Objective: To study the effectiveness and safety of abdominal active balloon closure during cesarean sections for patients with pernicious placenta previa (PPP).

Methods: A retrospective analysis was conducted on 140 patients with PPP and placenta accreta who were hospitalized and gave birth at the Third Affiliated Hospital of Zhengzhou University from June 2022 to December 2023. The patients were divided into two groups based on whether intervention was applied. The intervention group [intraoperative abdominal aortic balloon occlusion (IAABO) group] included 118 patients who received prophylactic abdominal aortic balloon occlusion during cesarean section. The routine group, without balloon occlusion, consisted of 22 patients.

Results: Compared to the routine group, the IAABO group had significantly lower intraoperative blood loss, blood transfusion volume, and hysterectomy rate (all P<0.05). Additionally, the IAABO group showed lower postoperative pain scores, shorter ambulation time, and higher patient satisfaction (all P<0.05). The neonatal intensive care unit admission rate and incidence of complications were also significantly lower in the IAABO group (both P<0.05).

Conclusion: Abdominal aortic balloon closure during cesarean sections can reduce bleeding and the need for blood transfusions in cases of PPP, thereby lowering the hysterectomy rate and the incidence of related complications.
