Abstract：As a new method for treating intracranial aneurysm,intravascular stent has been widely used in clinical practice and be-coming more and more popular.However,some of the implanted intravascular stent cannot meet the requirement of mechanics,or with-out discernible effect on tumour hemodynamic,but result in thrombus or rupture of aneurysms easily.With the application of structural statics,the resistance to bending and torsional deformation between latticed stent with rectangular section and spiralstent wove by mesh with circular cross section was analyzed and compared;then the latticed stent was implanted into cerebral aneurysm,and simulated fli-ud structure interaction to analyse the change of blood flow velocity,wall pressure and wall shear force.Result showed that both stent could provide good axial compliance without damaging radial support force,and the resistance to deformation of latticed stent was better than that of spiral stent;the indicators for hemodynamic were reduced dramatically after implanting the stent.Intravascular stent has great influence on the hemodynamics of intracranial anenrysms,It provides theoretical basis for clinic treatment of intracranial aneurysm.
