An in vitro patient-specific vascular model for simulating endovascular intervention is presented. Proposed vascular model reproduces the 3-dimensional vessel lumen structure using CT/MRI information with 13 μm resolution, and reproduce the physical properties of arterial tissue. Furthermore, in this paper, we propose a novel method to evaluate stress on vascular wall made by surgical operations. This method allows quantitatively real-time stress evaluation. Consequently, it allows interventionalists and developers to evaluate their materials in almost the same environment and with almost same manner as the practical endovasuclar treatment. And with these techniques, we constructed a comprehensive surgical simulation system, which reproduces whole human aorta structure (with more than 0.8 mm inside diameter). Proposed model, system and technique would provide helpful platforms for evaluating surgical procedures.
