Figure 1 . Materialise’s interactive medical image control system (MIMICS, version 19.0); (A) Coronal plane; (B) Transverse plane; (C) sagittal plane; (D) Three-dimension reconstruction model.
Figure 2 . The reconstruction model of the preoperative and postoperative aorta; Postoperative models of the aorta implanted with 80mm, 100mm, 120mm, and 150mm FETs. The morphological volume of the descending aorta FL in the long FET group (120mm and 150mm) was significantly reduced compared to the short FET group (80mm and 100mm).
Figure 3 . The total aorta; (A) Postoperative and preoperative volumetric changes of TTL/TFL. (B) Postoperative and preoperative volumetric changes of TFL/TAL. (C) Postoperative and preoperative volumetric changes of TTL/TAL. P*<0.05 .
Figure 4 . The descending aorta; (A) Postoperative and preoperative volumetric changes of DATL/DAFL. (B) Postoperative and preoperative volumetric changes of DATL/DAAL. (C) Postoperative and preoperative volumetric changes of DAFL/DAAL. (D) Postoperative and preoperative volumetric changes of DATL/TTL. P*<0.05 .
Figure 5 . The abdominal aorta; (A) Postoperative and preoperative volumetric changes of AbTL/AbFL. (B) Postoperative and preoperative volumetric changes of AbTL/AbAL. (C) Postoperative and preoperative volumetric changes of AbFL/AbAL. (D) Postoperative and preoperative volumetric changes of AbTL/TTL. P*<0.05 .
Figure 6 . Postoperative remodeling results of descending aorta; Coordinate: 0=short; FET group; 1=long FET group; result: 1=negative remodeling; 2=stable remodeling; 3=positive remodeling. P=0.0123 .
