Abstract

Purpose: To plan stent-grafting for aortic aneurysms with complicated morphology, we prepared life-sized aortic replicas by laser stereolithography using helical 3D-CT data. The accuracy of the replica was evaluated by measurement of vessel phantoms and clinical 3D-CT data. Method: An imaginary aortic wall was created from helical CT images of theaorta, and a hollow plastic replica was produced by laser stereolithogaphy. The accuracy of the replica was evaluated in five abdominal aortic aneurysms by experimental phantom studies and measurements of the replicas. Results: The mean difference in measurements between 3D-CT images and model vessels and between 3D-CT images and aortic replicas was 0.2 mm each. Therefore, the difference in measurements between real aortic aneurysms and the replicas was at most 0.4 mm. Conclusion: The accuracy of the replica is satisfactory, making it useful for preoperative evaluation and simulation for stent-grafting.
