Aortic pathologies comprised 5 acute Type-A-AD (38.5%), 4 acute Type-B-AD (30.8%), 1 chronic Type-B-AD (7.7%), and 3 chronic expanding residual Type-A-AD (23.1%). The rE (first [re-]entry distal to left subclavian artery [LSA] origin) had a median diameter of 15.5 mm (IQR: 9.4 mm) and was mostly located in zone 3 (61.5%), the outer curvature (61.5%), and 21.1 mm (IQR: 26.4 mm) distal to the LSA. The stented portion of the FET (FETSP) lengths measured 60-190 mm. FETSP proximal end was mostly located in zone 1 (38.5%) and at median distance of 28.2 mm (IQR: 26.5 mm) from the native LSA. FETSP distal end was mostly located in zone 5 (61.5%). Median calculated distance from rE to FETSP proximal end was 38.9 mm (IQR: 39.0 mm). Three patients (23.1%) died perioperatively; the others remained asymptomatic (follow-up: 13 mo [IQR: 15 mo]).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Large (re-)entries in the outer curvature of the distal aortic arch are common in patients with FET placement in the FL.
