CTA measurements include the areas of the false lumen (FL) of SMA proximal and distal to the stent, areas of the FL, true lumen (TL) of aorta, and the FL area to TL area ratios at zones 4\u20139.

Areas of SMA proximal and distal to the stent dropped sharply immediately after stenting, then slowly increased or fluctuated, but remained significantly smaller than preoperative values (P\u2009&amp;lt;\u2009.001 and P\u2009=\u2009.010).

The coeliac artery showed a significant trend of FL shrinkage up to 3 years (P\u2009&amp;lt;\u2009.050). The FL area to TL area ratios in zones 4, 8, and 9 showed a significant trend of decrease through 3 years (all P\u2009&amp;lt;\u2009.050), which was seen in zones 5\u20137 only through 2 years (all P\u2009&amp;lt;\u2009.050), not at 3 years.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>In patients with ATAAD complicated by mesenteric malperfusion, a reperfusion-first strategy with SMA stenting may induce significant FL shrinkage in the SMA, which was most pronounced within 30 days and persisted through 3 years. The frozen elephant trunk (FET) could induce significant TL expansion in zones 4\u20137, which was most obvious within 30 postoperative days. The TL expansion effect of the FET was more pronounced at proximal levels (zones 4\u20137) than distal segments (zones 8\u20139).<\/jats:p>\n
