Three-dimensional computing tomography centreline reconstructions before TEVAR\/FET and during the follow-up were conducted to measure aortic remodelling: false lumen thrombosis, TL expansion and aortic diameters at 10 and 20\u2009cm downstream the left subclavian artery, at the coeliac trunk and in the infrarenal aorta. All continuous variables are reported as median with first and third quartiles.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS<\/jats:title>\n                  <jats:p>Fifty-six consecutive patients were treated with TEVAR (n\u2009=\u200945) or FET (n\u2009=\u200911) in the acute (n\u2009=\u200916), subacute (n\u2009=\u200916) and chronic (n\u2009=\u200924) dissection phase. At a median follow-up of 6 (3\u201312) months, they showed a favourable TL expansion in the descending aorta, significantly higher in the acute [+9\u2009mm (5\u201312); P\u2009&amp;lt;\u20090.001] and subacute groups [+5\u2009mm (3\u20138); P\u2009=\u20090.039] than in the chronic group [+2\u2009mm (0\u20135)]. The dissection flap motility parameter TL strain was superior in the acute (P\u2009=\u20090.006) and subacute (P\u2009=\u20090.035) groups in comparison to the chronic group. The motile flap [TL strain &amp;gt;22.5% (median)] was associated with a higher TL expansion rate in the thoracic aorta (P\u2009=\u20090.009) and a comparable distal stent-induced new entry incidence (overall: 16%) in comparison to the immobile flap (P\u2009=\u20090.89).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>CONCLUSIONS<\/jats:title>\n
