Background Surgical management of traumatic aortic rupture (TAR) is controversial, specifically whether distal aortic perfusion modifies the outcome.
Hypothesis The outcome of patients who undergo repair of TAR is not dependent on the technique of repair.
Design Retrospective review.
Setting Tertiary care teaching hospital, level I regional trauma center.
Patients One hundred fifteen victims (aged 5-81 years) of blunt chest trauma with aortic tear, presenting between January 1, 1974, and June 30, 1999.
Methods Medical records were reviewed for prehospital and emergency department data, operative findings, and outcome. Statistical comparison was made using a paired 2-tailed t test.
Intervention Surgical repair of TAR with (group 1) or without (group 2) distal aortic perfusion.
Results Thirty-two patients in group 1 had TAR repair using active bypass (n = 18) or Gott shunt (n = 14). The clamp-and-sew technique was used in 83 patients (group 2). Primary repair was possible in 14 patients (44%) in group 1 and 69 patients (83%) in group 2. The average aortic cross-clamp time was 48 minutes for group 1 (range, 25-113 minutes) and 20 minutes for group 2 (range, 5-40 minutes) (P<.03). There was no significant difference in hospital mortality (6 [18.7%] of 32 vs 15 [18.1%] of 83) or the incidence of paraplegia (2 [6%] of 32 vs 5 [6%] of 83) between groups 1 and 2. During the last 15 years, 78 patients (73 in group 2) had repair of TAR with an operative mortality rate of 19.2%.
Conclusions Acute TAR remains a highly lethal injury with no change in prognosis during the last 2 decades. Repair of TAR using simple aortic cross-clamping alone is feasible in the majority of patients without increased mortality or spinal cord injury.
