Phantom-based experimental validation of fast virtual deployment of self-expandable stents for cerebral aneurysms
BACKGROUND Endovascular intervention using a stent is a mainstream treatment for cerebral aneurysms. To assess the effect of intervention strategies on aneurysm hemodynamics, we have developed a fast virtual stenting (FVS) technique to simulate stent deployment in patient-specific aneurysms. However, quantitative validation of the FVS against experimental data has not been fully addressed. In t...
متن کاملFast virtual deployment of self-expandable stents: Method and in vitro evaluation for intracranial aneurysmal stenting
INTRODUCTION Minimally invasive treatment approaches, like the implantation of percutaneous stents, are becoming more popular every day for the treatment of intracranial aneurysms. The outcome of such treatments is related to factors like vessel and aneurysm geometry, hemodynamic conditions and device design. For this reason, having a tool for assessing stenting alternatives beforehand is cruci...
متن کاملDeployment of self-expandable stents in aneurysmatic cerebral vessels: comparison of different computational approaches for interventional planning.
In the last few years, there has been a growing focus on faster computational methods to support clinicians in planning stenting procedures. This study investigates the possibility of introducing computational approximations in modelling stent deployment in aneurysmatic cerebral vessels to achieve simulations compatible with the constraints of real clinical workflows. The release of a self-expa...
متن کاملSelf-expanding and balloon-expandable stents in the treatment of carotid aneurysms: an experimental study in a canine model.
PURPOSE To assess the efficacy of metal stents for the treatment of different forms and sizes of carotid aneurysms. METHODS A total of 14 experimentally constructed aneurysms in dogs were treated with transfemorally placed balloon-expandable tantalum and self-expanding nitinol stents. RESULTS In 10 cases, stenting produced either immediate complete occlusion of the aneurysm (n = 7) or compl...
