Thoracic endovascular aortic repair (TEVAR) has become the first-line therapy for descending aortic disease. Recent studies have demonstrated that preventive revascularization of the left subclavian artery (LSA) in zone 2 TEVAR cases reduces the risk of neurological complications. However, there is no uniform consensus on the choice of revascularization techniques. Although carotid-subclavian bypass is considered the gold standard method, in situ fenestration techniques have also shown encouraging results. This study aims to compare the carotid-LSA bypass with in situ fenestration (ISF) for LSA revascularization and to discuss our treatment approach.
