Background
Our aim was to identify predictors of mortality and limb loss in iatrogenic and civilian arterial trauma.
Methods
Cases were identified by searching prospectively maintained registries. Multivariable logistic regression was used to identify independent outcome predictors.
Results
During the study period, 285 patients with arterial trauma were managed with endovascular (n = 20) or open (n = 265) repair. Iatrogenic injuries increased in frequency during the course of the study, from 23.9% during the first decade to 35.9 and 55.7% during the second and third decade, respectively (p < 0.001). Endovascular management increased in frequency during the course of the study, from 0% during the first decade to 5.1 and 11.1% during the second and third decade, respectively (p = 0.005). Mortality was 9.8%, and limb loss (in cases with injury of the aorta or limb arteries, n = 259) was 6.2%. Independent predictors of mortality included increased age (odds ratio, 95% confidence interval [OR, 95% CI] 1.05 (1.02–1.07), p < 0.001), blunt trauma (OR [95% CI] 4.8 (1.9–12.2), p = 0.001) and the number of RBC units transfused intraoperatively (OR [95% CI] 1.25 (1.1–1.4), p = 0.001). Independent predictors of limb loss included the first half of the study period (OR [95% CI] 3.9 (1.1–14.1), p = 0.04), lower extremity arterial trauma (vs upper extremity, aortic, common or external iliac artery trauma, OR [95% CI] 8.3 (1.9–35.7), p = 0.004), bone fracture (OR [95% CI] 16.9 (4.7–62.5), p < 0.001) and the number of RBC units transfused intraoperatively (OR [95% CI] 1.16 (1.02–1.33), p = 0.024).
Conclusion
Increasingly iatrogenic in cause and managed by endovascular methods, arterial trauma remains a problem associated with significant mortality and limb loss. Identification of unfavourable outcome predictors may help clinicians involved with arterial trauma to escalate the level of care.
