Classic teaching suggests that blunt thoracic aortic rupture (BTAR) results
from high-speed deceleration injury mechanisms, Our recent experience with
a patient who sustained fatal aortic rupture resulting from a low-speed cr
ushing injury emphasizes the importance of maintaining a high index of susp
icion for BTAR, even in patients with "low-risk" injury mechanisms. Several
potential pathophysiologic mechanisms of BTAR are discussed. Copyright (C)
