Research Abstract

To predict rupture of the aortic aneurysms from their microscopic structures, the relationship between rupture and structure of collagen in aortic wall was investigated. Firstly, a method to quantify local volume and direction of collagen fibers was established. Then, thin slices of the thoracic aortas were biaxially stretched during observation of collagen structure under a microscope. As a result, we found that local microscopic structures of collagen fibers strongly influenced its local strains, indicating that collagen structures may have important role on rupture of the aorta.
