Patients were categorized by LSA revascularization methods, including direct coverage without revascularization (Unrevascularized), carotid-subclavian bypass (CSB), fenestrated TEVAR (F-TEVAR).

There was no difference in 30-day and mid-term rates of mortality, stroke, and left upper extremity ischemia. CSB was more likely time-consuming than F-TEVAR [3.25 (2.83\u20134) vs. 2 (1.67\u20132.67) hours,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090], but there were no statistically significant differences in 30-day or midterm outcomes for CSB versus F-TEVAR.
