Contrast extravasation and hematoma volume as predictors of the need for embolization in patients with pelvic fractures

Angioembolization is effective and safe in patients with pelvic bone fractures arterial bleeding. However, there still no consensus regarding the indications for angiography after fractures. This study investigated predictors of embolization through a comparative analysis who had extravasation on angiography. From January 2009 to December 2021, 1431 were admitted single trauma center. After application exclusion criteria, 949 enrolled study. We divided into two groups identify bleeding: therapeutic (TE) group (n = 149) versus non-TE 800). Vital signs laboratory data significantly worse TE group, except Glasgow Coma Scale. When fracture patterns compared, vertical shearing type anteroposterior compression more common group. Multivariate logistic regression identified five embolization: systolic blood pressure <90 mmHg emergency department (odds ratio (OR) 2.63; 95% credible intervals (CI) 1.52–4.53; p 0.001), combined injury abdomen (Abbreviated Injury Scale ≥3) (OR 3.94; CI 2.23–6.97; < contrast enhanced computed tomography 30.41; 16.08–57.52; sacroiliac joint disruption 2.40; 1.35–4.28; 0.003), hematoma volume >25 mL 3.79; 2.06–6.98; 0.001). Systolic less than 90 mmHg, tomography, disruption, significant patients. Trauma surgeons’ clinical decision-making should consider features radiologic findings.
