Figure 2.

Three-dimensional digital models were constructed based on CTA and DSA images. Model A represents the idealized expansion of the stent to match the vessel diameter; model B signifies the initial partial expansion of the stent; model C portrays the subsequent over-expansion of the stent; and model D showcases the vessel model 18 months after the second over-expansion of the stent. Specifically, model C corresponds to a 3-day postoperative model depicted in Figure 1B, while model D corresponds to the 3D CTA images shown in Figure 1C.
