Nonoperative Management of Traumatic Aortic Pseudoaneurysms

NOM of traumatic aortic PSAs is a common practice in BTAI series reporting lesion-specific management, and is associated with low rates of treatment failure. These findings suggest that routine early repair may not be required for traumatic PSAs, particularly for lesions limited to <50% of the aortic circumference. Definitive repair can be delayed until patient stability and repair timing can be guided by assessment of lesion stability on follow-up imaging.
