Outline of Final Research Achievements

Stent graft changes chronologically after implantation into the abdominal aortic aneurysm, and the behaviors differed among devices. We revealed that mechanical factors such as curvature (angulation) or torsion changes gradually after the implantation and numerically expressed and visualized, with our own modeling system. We are able to reveal the risk of migration case-specifically, which is considered to be helpful clinically.
