Traumatic thoracic aortic injuries are serious and may be associated with high morbidity and mortality. Endovascular stent grafting is now an established treatment option which often requires proximal landing zone extension through left subclavian artery (LSA) origin coverage. This in turn can lead to downstream ischaemic complications which may be lessened by LSA revascularisation. This study investigates the consequence of LSA coverage and potential benefit of revascularisation.
