We included 285 patients with acute type A\/B, chronic type A\/B, and residual dissection. Patients were divided into normal arch group (n\u2009=\u2009216) and arch anomalies group (n\u2009=\u200969), including aberrant right subclavian artery, bovine trunk, arch vertebral artery, and gothic arch.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Overall in-hospital mortality was 15.4% (17.4% in arch anomalies vs 14.8% in arch normal). In-hospital thoracic endovascular aortic repair (TEVAR) occurred in 7.2% (n\u2009=\u20095) of patients with arch anomalies. Stent graft-induced new entry tear at follow-up was 26.1% in arch anomalies vs 17.1% in arch normal group. Long-term survival in the overall patients was not different between the 2 groups (P\u2009=\u2009.383). In the subgroup of patients treated for chronic aortic dissection, freedom from TEVAR was higher in those with normal arch anatomy (P\u2009=\u2009.026).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Aortic arch anomalies, especially in chronic dissection, were associated with increased endovascular reintervention.
