Association of traumatic brain injury with management and outcomes of patients with blunt thoracic aortic injury.

BACKGROUND

30% of patients with blunt thoracic aortic injury (BTAI) can have concomitant traumatic brain injury (TBI), with mortality nearing 20%. Conflicting blood pressure goals may influence decision and timing of thoracic endovascular aortic repair (TEVAR). This study analyzed management and outcomes in patients with concomitant TBI/BTAI.

METHODS

Patients with concomitant TBI/BTAI and BTAI were identified in our trauma registry. Descriptive statistics and logistic regression compared management and outcomes.

RESULTS

Twenty patients had concomitant TBI/BTAI. 46 patients had BTAI alone. 9(13%) patients with concomitant TBI/BTAI and 30(45%) patients with BTAI alone underwent TEVAR. There was no difference in overall mortality (OR 0.29, 0.05-1.55 CI, p ​= ​0.12), aortic-related mortality (x2 3.51, p ​= ​0.06), incidence of TEVAR (x2 1.59, p ​= ​0.10) or timing to TEVAR (t ​= ​-1.6056, p ​= ​0.06) between patients with concomitant TBI/BTAI and BTAI alone.

CONCLUSION

There was no difference in outcomes or interventions in patients with TBI/BTA vs BTAI alone in this small, hypothesis-generating single institutional trial.
