Ascending TEVAR was feasible, safe, and effective for AAPs and PAUs. In a very select subset of lesions, midterm results were favorable, with both standard and custom-designed endografts.
Management of the left subclavian artery (LSA) during thoracic endovascular aortic repair (TEVAR) has generated considerable debate, especially in terms of prevention of stroke and spinal cord ischemia (SCI). 1-8 The most recent guidelines advocated selective LSA revascularization in most thoracic aortic pathologies. 9-11 Although different techniques and approaches are in use, 12-15 there has been no prior study or analysis comparing open LSA revascularization with other options such as chimney grafts (CGs). The aim of this study was to examine the results of TEVAR with isolated LSA revascularization using carotid-subclavian bypass (CSbp) or CGs. Methods Study Design and Study Sample A retrospective multicenter, observational study (ISLA) was conducted to identify all patients with acute or chronic thoracic aortic lesions who underwent TEVAR with isolated LSA revascularization using either CSbp or CGs from 802581J ETXXX10.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
