Effectiveness of Prophylactic Bilateral Internal Iliac Artery Balloon Occlusion in Reducing Intraoperative Blood Loss in Placental Abnormalities: A Prospective Non-Randomised Comparative Study
Abstract: Background: Placental abnormalities such as placenta previa and placenta accreta spectrum are important causes of severe obstetric haemorrhage. Control of intraoperative blood loss during lower segment caesarean section remains a major challenge. Prophylactic internal iliac artery balloon occlusion has been suggested as an adjunct to reduce bleeding, though evidence is still evolving. Methods: This prospective non-randomised comparative study included 60 pregnant women with placental abnormalities undergoing elective lower segment caesarean section. Thirty underwent prophylactic bilateral internal iliac artery balloon occlusion and 30 received standard care. Primary outcome was intraoperative blood loss. Statistical analysis was performed using appropriate tests, with p<0.05 considered significant. Results: Mean intraoperative blood loss was significantly lower in the balloon group (820 ± 210 mL) compared to the control group (1280 ± 320 mL; p<0.001). Duration of surgery was shorter (82.5 vs 104.3 minutes; p<0.001), and haemoglobin drop was less (1.6 vs 3.1 g/dL; p<0.001). Postpartum haemorrhage (10.0% vs 36.7%; p=0.018) and ICU admission (13.3% vs 40.0%; p=0.020) were also reduced. Balloon placement was successful in 96.7% of cases, with minimal complications (6.7%). Conclusion: Bilateral internal iliac artery balloon tamponade appears to be an effective adjunct in reducing intraoperative blood loss and improving perioperative outcomes in patients with placental abnormalities undergoing caesarean section.
