THE SALVAGEABILITY OF PATIENTS WITH POST-TRAUMATIC RUPTURE OF THE DESCENDING THORACIC AORTA IN A PRIMARY TRAUMA CENTER

Abstract

If uniform early diagnosis is accomplished, two thirds of patients with rupture of the proximal descending aorta seen at a primary trauma treatment center are potentially salvageable. Currently the survival rate is only one half of this optimum figure (31%). One third of 39 patients with acute rupture of the proximal descending thoracic aorta studied had lethal concomitant injuries and were unsalvageable. Twenty-six patients were potentially salvageable; twelve (46%) survived. Eight potential survivors (31%) died because their aortic rupture was not diagnosed or because it was not promptly diagnosed. Eighteen of the potentially salvageable patients (69%) underwent aortic repair; two thirds survived. Aortic rupture was uniformly diagnosed earlier in the more critically injured patients and thus they underwent aortic repair earlier. One half of the 12 patients in whom thoracotomy was instituted within 6 hours of admission survived; six patients who underwent aortic repair more than 6 hours after admission survived.
