Thoracic Endovascular Aortic Repair With Left Subclavian Artery Coverage Is Associated With High 30-Day Stroke Incidence With or Without Concomitant Revascularization

Abstract

Review of the National Surgical Quality Improvement Program registry from 2005 to 2017 The stroke incidence was 2% after elective thoracic endovascular aortic repair (TEVAR) without left subclavian artery (LSA) coverage compared with 5% with LSA coverage (P < .001). In TEVARs with LSA coverage, the stroke incidence was 7.5% when the LSA was concomitantly revascularized vs 4.4% without concomitant revascularization. LSA coverage was significantly associated with stroke both with and without concomitant revascularization. Stroke after TEVAR with LSA coverage occurs frequently in the real-world setting, and concurrent LSA revascularization was not associated with a lower stroke incidence.
