Left Subclavian Artery Revascularization for Thoracic Aortic Stentgrafting: Single Center Experience in 101 Patients

Introduction - Endovascular treatment of thoracic aortic pathology (TEVAR) requires a landing zone of at least 20mm in length, necessitating coverage of the left subclavian artery (LSA) in approximately 40% of the patients.1 Coverage of the LSA may increase the risk of ischaemic stroke, spinal cord ischaemia (SCI) and/or left arm claudication. Besides some endovascular options to preserve LSA flow, in the majority of cases the LSA is surgically revascularized by either a carotid-to-subclavian bypass graft or subclavian-carotid transposition.
