“…Application of a stent into the parent artery alters the intra-aneurysmal flow pattern that facilitates thrombosis and reduction of coil compaction in the region of inflow zone and prevents subsequent regrowth of aneurysm [ 7 ]. Conversely, the Y-stenting might have changed the hemodynamics of the aneurysm blood flow, which might be a contributory factor for rupture [ 8 ].…”

Endovascular treatment for a wide-neck anterior communicating artery (AcomA) aneurysm remains technically challenging. Stent-assisted embolization has been proposed as an alternative of treatment of complex aneurysms. The X-configuration double-stent-assisted technique was used to achieve successful coiling of wide-neck AcomA aneurysm. Implanted stent can alter intra-arterial flow. Follow-up angiograms 4 months later showed flow changes due to used X-technique of stents implantation and filling of the anterior cerebral artery from the opposite internal carotid artery.

Suppression of Wall Shear Stress inside Intracranial Aneurysms by Simple Stents

et al. 2018

The effect of a simple bare-metal stent on suppression of wall shear stress inside a spherical intracranial aneurysm model was experimentally examined by two dimensional particle image velocimetry in vitro. The flow model simulated an intracranial aneurysm induced both at the side wall and at the apex of bifurcation in the cerebral arteries. In order to assess the simple bare metal stent characteristics, the variation of wall shear stress was examined using both stented and non-stented models. The flow behavior inside the stented aneurysm was not smooth and wall shear stress was significantly smaller inside the aneurysm. For both models, the maximum and the temporal and spatial averaged wall shear stress in the stented model is reduced by at least 50 % smaller than those in the non-stented models. Stent deployment effectively suppresses the temporal and spatial variations, and the magnitude of wall shear stress. Consequently, even simple stent might be an effective treatment to retard the progress of cerebral aneurysms.

Repression of wall shear stress inside cerebral aneurysm at bifurcation of anterior cerebral artery by stents

et al. 2015

The effect of a simple bare metal stent on repression of wall shear stress inside a model cerebral aneurysm was experimentally investigated by two-dimensional particle image velocimetry in vitro. The flow model simulated a cerebral aneurysm induced at the apex of bifurcation between the anterior cerebral artery and the anterior communicating artery. Wall shear stress was investigated using both stented and non-stented models to assess the simple stent characteristics. The flow behavior inside the stented aneurysm sac was unusual and wall shear stress was much smaller inside the aneurysm sac. Stent placement effectively repressed the temporal and spatial variations and the magnitude of wall shear stress. Hence, there is an effective possibility that would retard the progress of cerebral aneurysms by even simple stent.
