Previous hemodynamic studies have been based on comparisons between post-ruptured and unruptured aneurysms. Nevertheless, changes of aneurysm morphology after rupture render these results unreliable. Moreover, pressure, age, gender, and the morphology of the parent artery also influence these results. Therefore, in the present study, we identified hemodynamic and morphological characteristics of aneurysms prior to rupture using twelve mirror aneurysms.Materials and Methods: From our database, we retrospectively analyzed twelve mirror aneurysms (MANs) prior to rupture. Each mirror aneurysm was divided into the prior to rupture or the unruptured group. Patient-specific models were reconstructed from three-dimensional (3D) images of all patients. Hemodynamic and morphological factors were analyzed and compared.Results: Compared with the unruptured side of MANs, aneurysms prior to rupture were significantly larger and significantly more irregular in shape; they also had significantly higher aspect ratio (AR), size ratio (SR), undulation index (UI), ellipticity index (EI), percentage of low wall shear stress area (LSA) and significantly lower normal wall shear stress (NWSS). The oscillatory shear index (OSI) and nonsphericity index (NSI) in the aneurysms prior to rupture were non-significantly higher than those of the unruptured group.Conclusion: MANs prior to rupture may be extremely useful models to assess the risk of aneurysm rupture. Larger size, irregular shape, higher AR, SR, UI, NI, and lower WSS may be associated with aneurysms at risk for rupture.Keywords: mirror aneurysms, computational fluid dynamics, hemodynamics, morphological, rupture

While scientific and technological progress and economic development have improved the state of human life, they have also brought a series of hazards to human survival. Therefore, sustainable development has become an inevitable trend for development in various fields. Patchwork art is a typical traditional art form. No matter now or in the future, only by absorbing the essence of culture, deeply exploring the harmonious relationship between man and nature, and adhering to the road of sustainable development can we realize the vitality of modernization. This article focuses on the concept of sustainable development and provides theoretical knowledge and methodological guidance for modern patchwork art design. Taking the work “Hui Yu Men Ting” as an example, it discusses the sustainable design research of the use of waste denim clothing for the creation of patchwork art from the aspects of material selection, creative concept, and expression techniques.
