ABSTRACT: Aortic coarctation is a fatal cardiovascular disease. For Stanford type B aortic coarctation, aortic endovascular isolation (TEVAR) is currently the treatment of choice and is far less invasive than open surgery. Standard TEVAR involves the use of a stent graft to cover the proximal breach, which prevents the expansion of the false lumen and promotes its thrombosis, which in turn leads to therapeutic results. During implantation of endovascular grafts, Left Subclavian Artery (LSA) coverage has been associated with the development of a variety of complications, including stroke, spinal cord ischemia, upper extremity ischemia, etc. Therefore, the key to endoluminal treatment of aortic arch disease lies in the preservation or reconstruction of the branching arteries over the arch. Currently, most medical centers in China tend to reconstruct the LSA. This article provides a review of the methods and advantages and disadvantages of reconstructing the LSA in TEVAR, as well as a prospective view of reconstructing the supra-arch artery in the future.
