What is the recommended initial approach when blunt aortic injury is suspected in a polytrauma patient?

Rapid confirmation with CT angiography is essential because it provides definitive visualization of the thoracic aorta and guides immediate management. In a polytrauma patient with suspected blunt aortic injury, you want to confirm injury and assess its extent before committing to repair, since many suspected cases are not actually present and unnecessary surgery can cause harm. While awaiting imaging, control blood pressure to reduce aortic wall stress (keep systolic around 100–120 mmHg and avoid rapid, forceful blood pressure swings) and involve vascular surgery early so definitive treatment planning can begin. CT angiography offers precise injury characterization that informs whether endovascular repair or open repair is needed, and it sets up a safe, targeted approach. Bedside FAST cannot assess the thoracic aorta and is insufficient for this diagnosis, and observation alone is inadequate given the risk of progression. Immediate repair without imaging risks operating without knowing the injury’s extent.
