Trauma and Emergency Care Studies

Angiography with selective angioembolization (SAE) is safe and effective in addressing bleeding in patients with renal trauma. However, there are no validated criteria to predict SAE efficacy.To evaluate factors predictive of SAE failure after moderate- to high-grade renal trauma.TRAUMAFUF was a retrospective multi-institutional study including all patients who underwent upfront SAE for renal trauma in 17 French hospitals between 2005 and 2015.The primary outcome was SAE efficacy, defined as the absence of repeat SAE, salvage nephrectomy, and/or death for each patient.Out of 1770 consecutive patients with renal trauma, 170 (9.6%) with moderate- to high-grade renal trauma underwent SAE. Overall upfront SAE was successful in 131 patients (77%) and failed in 39 patients: six patients died after the embolization, ten underwent repeat SAE, 22 underwent open nephrectomy, and one underwent open surgical exploration. In multivariate logistic regression analysis, gross hematuria (odds ratio [OR] 3.16, 95% confidence interval [CI] 1.29-8.49; p=0.015), hemodynamic instability (OR 3.29, 95% CI 1.37-8.22; p=0.009), grade V trauma (OR 2.86, 95% CI 1.06-7.72; p=0.036), and urinary extravasation (OR 3.49, 95% CI 1.42-8.83; p=0.007) were predictors of SAE failure. The success rate was 64.7% (22/34) for patients with grade V trauma and 59.6% (31/52) for those with hemodynamic instability. The study was limited by its retrospective design and the lack of a control group managed with either surgery or surveillance.We found that gross hematuria, hemodynamic instability, grade V trauma, and urinary extravasation were significant predictors of SAE failure. However, success rates in these subgroups remained relatively high, suggesting that SAE might be appropriate for those patients as well.Selective angioembolization (SAE) is a useful alternative to nephrectomy to address bleeding in patients with renal trauma. Currently, there are no validated criteria to predict SAE efficacy. We found that gross hematuria, hemodynamic instability, grade V trauma, and urinary extravasation were significant predictors of SAE failure.
