Key result
Double stenting and anterior densified stents reduced intra-aneurysmal mean velocity by 90.39% and 80.29% respectively in a computational cerebral aneurysm model.
Why the study?
Does the use of different stent forms (double stenting or variable-spacing stenting) improve hemodynamic factors and reduce rupture risk in a cerebral aneurysm model?
Does the use of different stent forms (double stenting or variable-spacing stenting) improve hemodynamic factors and reduce rupture risk in a cerebral aneurysm model?
Computational modeling demonstrates that double stenting and anterior densified stenting significantly reduce intra-aneurysmal velocity and wall shear stress, potentially lowering the risk of cerebral aneurysm rupture.
May guide stent optimization in aneurysm models; leaves open clinical translation to rupture prevention.
An ideal cerebral aneurysm model with different stent forms is established. By using the single-relaxation-time (SRT) lattice Boltzmann method (LBM) to solve the flow field, the blood flow characteristics in the aneurysm under different conditions are studied numerically. The intra-arterial stenting of saccular aneurysms at different Reynolds numbers and the feasibility of new stenting forms such as double stenting and variable-spacing stenting in the aneurysms are explored. The hemodynamic factors such as velocity distribution and wall shear stress (WSS) in the aneurysm are analyzed. Numerical results show that the risk of aneurysm rupture is mainly centralized at the right corner of the aneurysm. Intervention of stents in the aneurysm can effectively reduce the intra-aneurysmal velocity and WSS, and decrease the danger of aneurysm rupture during strenuous exercise or emotional excitement. At the same time, the intervention of a double stent and the stent shape with a dense anterior part in the aneurysm has certain advantages in preventing aneurysm rupture. The intra-aneurysmal mean velocity reduction can reach 90.39% and 80.29% after the intervention of the double stent and the anterior densified stent respectively.
