1 This complication occurs more frequently when the left subclavian artery (LSA) is covered, compromising anterior cord blood flow from the left vertebral artery.
2 Prophylactic revascularization utilizing left common carotid artery (LCA) to LSA bypass/transposition has been reported to reduce the incidence of paraplegia, particularly during long segment stenting of the thoracic aorta. …
