Lit Matters 2: Anticoagulation and Beta-Blockers for Blunt Aortic Injury?

Blunt traumatic aortic injury is a high-mortality trauma diagnosis, and thoracic endovascular aortic repair has largely replaced open repair for many patients. Current evidence increasingly favors delayed TEVAR over repair within 24 hours, with aggressive blood pressure and impulse control as the key bridge from the ED.

Timing and Medical Stabilization in BTAI

• Delayed TEVAR signal: Delayed thoracic endovascular repair after blunt aortic injury was associated with lower 30-day mortality than repair within 24 hours, a practice-changing signal from the available observational literature.
• Early repair tradeoff: Early TEVAR shortened ICU stay by about 3 days, but that speed advantage did not translate into better short-term survival and may come at a mortality cost.
• Complication profile: Delayed repair did not show higher rates of stroke, DVT, sepsis, or renal failure, which supports taking time to stabilize the patient before definitive aortic intervention.
• Impulse control bridge: BTAI behaves like a shear-stress problem, so ED management hinges on tight blood pressure control and beta-blockade before the graft ever goes in. We get into the bedside rationale in the episode.
• Anticoagulation deviation: Pre-procedural anticoagulation may be safe in selected blunt aortic injury patients, a notable departure from usual trauma reflexes and one of the more nuanced decisions around TEVAR timing.
• Evidence limits: The mortality advantage for delayed TEVAR comes from seven nonrandomized studies, so the signal is compelling but still vulnerable to selection bias and confounding by injury severity.
