Preventive Percutaneous Intra-Aortic Balloon Occlusion Minimizes Hemorrhage in Anterior Acetabular Fracture Surgery

Overview

This retrospective propensity score-matched study evaluated the efficacy of prophylactic percutaneous intra-aortic balloon occlusion (IABO) in reducing intraoperative blood loss during open reduction and internal fixation (ORIF) of acetabular fractures via anterior approaches. The findings demonstrate that IABO significantly minimizes hemorrhage, improving surgical conditions and potentially enhancing patient safety.

Background

ORIF for acetabular fractures, especially via anterior approaches, is technically challenging due to deep anatomical location and is associated with substantial intraoperative bleeding. Excessive blood loss complicates fracture reduction and fixation and can threaten patient survival. While various blood conservation methods exist, none have shown substantial impact. IABO, a technique used to control hemorrhagic shock in trauma and oncologic surgeries, has not been systematically evaluated in acetabular fracture fixation until now.

Data Highlights

Key Findings

• Prophylactic percutaneous IABO was successfully implemented in 24 patients undergoing anterior approach ORIF for acetabular fractures.
• IABO significantly reduced intraoperative blood loss compared to matched controls without balloon occlusion.
• The balloon was positioned in Zone 3 of the aorta (between renal arteries and aortic bifurcation) under fluoroscopic guidance.
• Each balloon inflation was limited to 40 minutes with mandatory 10-minute deflation intervals to minimize ischemic risks.
• Propensity score matching balanced key confounders such as age, sex, fracture type, BMI, and timing of surgery, strengthening the validity of comparisons.

Clinical Implications

Prophylactic use of percutaneous IABO during anterior acetabular fracture fixation can effectively reduce intraoperative hemorrhage, facilitating safer and more controlled surgical procedures. Surgeons should consider IABO in high-risk patients or when significant bleeding is anticipated, while adhering to inflation time limits to reduce ischemic complications.

Conclusion

This study supports the clinical utility of prophylactic percutaneous IABO in minimizing blood loss during anterior approach acetabular fracture surgery, potentially improving surgical outcomes and patient safety.
