Abstract: Objective To investigate feasibility and validity of endovascular aortic repair (EVAR) of traumatic thoracic aortic injuries (TTAI).Methods A retrospective analysis was conducted on data of 13 patients with TTAI.Pathological changes were evaluated by spinal CT angiography (CTA) preoperatively and re-evaluated by digital subtraction angiography (DSA) in EVAR.CTA was performed again to confirm therapeutic effects at postoperative 3,6,12 months and annually thereafter.Results All patients had successful EVAR.Complete or partial cover of left subclavian artery was observed in four patients.Endoleak in angiography shortly after stent delivery was noticed in three patients.However,endoleak disappeared in one patient after short stent placement for twice; endoleak was evidently decreased in one patient after balloon dilation.Follow-up was performed for another patient with slight endoleak.A total of 12 patients were followed up,which showed no complications,such as endoleak,ischemia of left upper extremity,paralysis or stent-graft migration.Conclusion EVR is safe and effective in treatment of TTAI.
