In　order　to　make　more　precise　analysis　on　hemodynamics　in　boundary　layer,　it　is　necessary　to　investigate　the　approaches　to　the　reconstruction　of　numerical　simulation　oriented　patient-specific　model　of　aortic　arch　aneurysm　that　can　perform　particular　meshing　in　boundary　layer.　A　solid　model　of　aortic　arch　aneurysm　was　reconstructed　using　CAD　software　Geomagic　and　Pro/E,　and　a　simplified　model　of　stent　for　the　intervention　of　the　aortic　arch　aneurysm　was　also　created.　These　models　were　transferred　to　ANSYS　software,　and　divided　into　several　parts.　Particular　meshing　was　performed　especially　in　boundary　layer　and　around　the　stents　so　as　to　obtain　the　finite　element　model　particularly　suitable　for　numerical　simulation　of　hemodynamics.　Simulation　was　performed　to　verify　the　applicability　of　the　constructed　model.　The　results　indicate　the　finite　element　model　can　be　employed　to　simulate　hemodynamics　in　aortic　arch　aneurysm　treated　with　endovascular　stent.　The　approaches　of　modeling　were　applicable　and　could　be　used　as　a　reference　for　similar　model　reconstruction.
