In this article, a pair of intracranial aneurysms, both located  at two sides of the partent artery and one aneurysm sac had a branch vessel, were treated with two kinds of flow diverting stents: LVIS and Pipeline by rapid virtual deployment method. The blood flow in the pair of aneurysms before and after treatment was simulated by computational fluid dynamics and the hemodynamic parameters were calculated. Analyzing the numerical results, it was observed that velocity reduction of treated aneurysms with Pipeline was much larger than with LVIS, wall shear stress on the treated aneurysms  with Pipeline was much smaller than with LVIS. It is concluded that Pipeline is more effective to occlude the aneurysm than LVIS, but the aneurysm treated with Pipeline has higher rupture risk than with LVIS.
