- W2387833449 abstract "Objective To study the comparison of blood flow in the aortic dissection and thoracic aortic,and provide theoretical basis for clarifying the pathogenesis of aortic dissection disease through the hemodynamic parameters of aortic dissection based on CT images.Methods Patient A,male,46-year-old,with normal thoracic aortic;patient B,female,33-year-old,with cavity form of DeBakey Ⅲ aortic dissection were enrolled.CT images was DICOM format,layer distance 0.5 mm,plane resolution 512 × 512 and pixel size 0.5 mm.The medical image post-processing software was applied to reconstruct the clinical two-dimensional CT reconstruction of medical images,and the three-dimensional model for simulation of the computer aided design(CAD) model was obtained.The computational fluid dynamics(CFD) software was applied to simulate the blood flow within the thoracic aorta,and the relevant hemodynamic parameters were obtained.Results The hemodynamic parameters of thoracic aorta at different time during a cardiac cycle were calculated.Conclusion The blood flow in aortic dissection during the cardiac cycle is complex,which shows as the large changes in wall stress,multiple vortex phenomena at the openings,thus it demonstrates there is a certain relationship between the complex blood current pattern in aortic dissection and the pathogenesis of aortic dissection disease." @default.
