In endovascular aortic repairs with stentgrafts, preoperative simulations were performed with full-scale 3D vascular models manufacturing by laser prototyping from CT data. These simulations contributed to the decision of the strategy and the precise managements for endovascular stentgrafting. Also, There were no significant differences in the impact upon clinical results between the preoperative simulations with use of the vascular models and the virtual simulations on the 3D workstation. These results certified the validity of the virtual simulation on the 3D workstation, and many clinical successes in the endovascular repairs for aortic aneurysms and dissections were achieved with this method.
