Aortic remodeling after surgery. (A) Proportions of different FL thrombosis levels in the stented thoracic aorta at different time points after surgery. (B) Proportions of different FL thrombosis levels in the unstented thoracic aorta at different time points after surgery. (C) Proportions of different FL thrombosis levels in the abdominal aorta at different time points after surgery. (D) The 3D reconstruction of aortic CTA shows the appearance of the SIS graft prosthesis after AAR+TAR+FET implantation surgery. (E–H) The axial view of aortic CTA presents comparisons of the aorta preoperatively and 3 months postoperatively in the same patient who underwent Bentall+AAR+TAR+FET implantation. (E) At the pulmonary artery bifurcation level, the intimal flap, TL and FL could be seen clearly in the ascending aorta and descending aorta preoperatively. (F) The ascending aorta was replaced with a terylene vascular graft, and the FL completely disappeared after FET implantation. (G) At the T10 level, the intimal flap, TL and FL could be seen clearly in the descending aorta preoperatively. (H) The FL disappeared in the unstented region by 3 months postoperatively. FL, false lumen; 3D, three-dimensional; CTA, computed tomography angiography; AAR, ascending aorta replacement; TAR, total arch replacement; FET, frozen elephant trunk; TL, true lumen.
