We report a rare case of severe distal aortic arch deformation with flexural deformity occurring in the long-term follow-up period after total aortic arch replacement with a frozen elephant trunk stent-graft (TAR-FET) (TAR-FET) for aortic dissection. The patient required re-arch replacement using FET and staged TEVAR, which completely restored the morphological deformity. Caution is warranted regarding aortic wall vulnerability and the spring-back force of FET, highlighting the importance of long-term follow-up.
