OBJECTIVE: To evaluate the contribution of aortography in the management of
stable patients with transmediastinal gunshot wounds. DESIGN: Retrospective
review of clinical records. SETTING: Level I urban trauma center. PATIENTS:
Forty-three patients with aortic or esophageal gunshot injuries.
INTERVENTIONS: Patients who were stable after initial resuscitation
underwent aortography followed by esophagography. MAIN OUTCOME MEASURES:
Hemodynamic status on admission, time devoted to diagnostic workup,
surgical (or autopsy) findings, morbidity, and mortality. RESULTS: There
were 24 esophageal injuries and 20 aortic injuries. Patients with aortic
injuries were less often stable for aortography (10% vs 42%; P = .02), and
fewer of them survived (15% vs 58%; P = .01). In no patient was the aortic
injury initially detected by aortography. Stable patients with esophageal
injuries experienced an average 11-hour interval between injury and surgery
(nearly 3 hours attributable to aortography). CONCLUSION: Esophageal
evaluation should precede aortography in the workup of stable patients with
transmediastinal gunshot wounds.
