case_images: The segmentation process included the whole thoracic aorta (TA) and supra-aortic vessels (Figure 1A). At the level of the LSA, the maximum diameter and area were calculated for each cross-section (Figure 1B). The results of the CFD simulations revealed a minimal decrease in the flow rate through the LSA after the intervention, with a percentage difference in flow volume between the 3DPRE and 3DPOST configurations during the systolic phase of only 2.38% (Figure 1C). The analysis showed differences in cross-sectional areas and diameters at the initial portion of the LSA, ranging from 0.11 to 1.49 cm2 and 0.04 to 0.64 cm, respectively (Figure 1).
