Abstract

Background: A limited number of studies have been conducted on the relationship between the geometry of the ANEURYSM and artery of origin, and its effects on the HEMODYNAMIC parameters. The present study was aimed to analyze the DEFLECTION ANGLE between U-shaped and S-shaped ANEURYSMs and the artery of origin as one of the geometrical parameters in order to determine its effect on intra-ANEURYSMal HEMODYNAMICs.Methods: In this study, DEFLECTION ANGLEs of 0, 45, 90, 135, and 180 degrees were considered for U-shaped and S-shaped ANEURYSMs. In this way, the amount and distribution of shear stress on the ANEURYSM wall, the affected area, and the susceptible area for remodeling of the ANEURYSM wall were investigated.Results: According to the results, 135o angle for the U-shaped ANEURYSM and 90o angle for the S-shaped ANEURYSM were the most dangerous angles for ANEURYSM growth. In addition, 90o and 180o angles evoking posterior and abdominal aortic ANEURYSMs in U- and S-shaped ANEURYSMs were shown as the most dangerous angles for ANEURYSM rupture.Conclusion: The findings of the current study can be effective in estimating the probable risk and clinical decision making in cerebral ANEURYSM patients.
