Abstract

Two patients with traumatic rupture of the mid-descending aorta successfully repaired are presented. Most clinical series of aortic tears do not include this entity. A review of the world literature reveals only 9 previous cases. In 6 of the 11 patients the diagnosis was either missed or delayed. In 4 patients the diagnosis was delayed or missed because of the absence of a superior mediastinal hematoma, and in 2 patients the diagnosis was delayed because of inadequate (single-plane) aortography. Suspicion may be lacking because of absence of the upper mediastinal hematoma considered to be the sine qua non for the diagnosis of aortic rupture. Although deceleration is considered to be the mechanism of injury in tears at the isthmus, severe hyperextension (often associated with fracture dislocation of the underlying thoracic vertebra) is considered to be the causative factor in descending aortic tears. Experience with the 2 patients presented here demonstrates that a high index of suspicion and complete two-plane aortography is required to avoid the potential for catastrophic outcome subsequent to overlooking a tear of the mid-descending aorta.
