Short-term results of left subclavian artery salvage in blunt thoracic aortic injury with short proximal landing zones

TEVAR for BTAI in patients with short proximal landing zones of 10 to 20 mm as well as in select patients with landing zones of 5 to 10 mm appears to be safe and efficacious. The aorta demonstrates no residual injury after TEVAR, with the graft acting potentially more as a bridge to allow healing. Long-term issues regarding LSA coverage have been difficult to ascertain and to evaluate because of historically poor follow-up in this population of patients. However, potential issues with LSA coverage and revascularization may be avoided by preserving the subclavian artery even with shorter proximal landing zones.
