The primary outcomes were LSCA-related complications, including stroke, dizziness, and upper limb ischemia.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Thirty-six patients underwent TEVAR with an assigned management strategy for the LSCA. Two patients in the direct coverage group had transient dizziness, without experiencing a major embolic stroke or upper limb ischemia. Of the 16 patients undergoing LSCA reconstruction, the fenestrated intervention had a shorter operative time than the bypass (68 vs. 240\u2005min,\n                      <jats:italic>P<\/jats:italic>\n                      \u2009=\u20090.001) and had lower total hospitalization costs (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009=\u20090.001). Two type II endoleaks resolved spontaneously by 1-month follow-up.
