Left Subclavian Artery Coverage during Endovascular Repair of Blunt Thoracic Aortic Injuries: Extending the Proximal Seal Zone May Increase the Risk of Stroke

The location of blunt thoracic aortic injuries (BTAI) frequently results in inadequate proximal seal for thoracic endovascular aortic repair (TEVAR) unless the stent graft is advanced into aortic zone 2, covering the left subclavian artery. Although well described for aneurysm treatment, the risks associated with this coverage are perceived as less important in trauma, with up to 50% reported rates of left subclavian artery coverage (LSAC) during BTAI repair. We aimed to estimate current rates of LSAC during TEVAR for BTAI and assess the complications associated with LSAC.
