- Systematic review and meta-analysis on internal iliac artery balloon occlusion (PPBO) in placenta previa and placenta accreta spectrum (PAS).
- PPBO aimed to reduce perioperative bleeding, but efficacy primarily based on retrospective studies.
- Three RCTs with 167 women analyzed; PPBO associated with increased RBC transfusion (4.52 vs 3.70 units).
- Higher postoperative fever incidence and longer hospitalization in PPBO group.
- Low certainty evidence suggests PPBO may not reduce bleeding as intended.
