Flow diversion treatment: intra-aneurismal blood flow velocity and WSS reduction are parameters to predict aneurysm thrombosis

Philippe Reymond, Luca Augsburger, Daniel Ruefenacht

To evaluate the haemodynamic changes induced by flow diversion treatment in cerebral aneurysms, resulting in thrombosis or persisting aneurysm patency over time. Eight patients with aneurysms at the para-ophthalmic segment of the internal carotid artery we ...

Fast virtual deployment of self-expandable stents: Method and in vitro evaluation for intracranial aneurysmal stenting

Luca Augsburger, Daniel Ruefenacht

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 aneur ...

Intracranial Stents Being Modeled as a Porous Medium: Flow Simulation in Stented Cerebral Aneurysms

Nikolaos Stergiopoulos, Philippe Reymond, Luca Augsburger

Intracranial aneurysms may be treated by flow diverters, alternatively to stents and coils combination. Numerical simulation allows the assessment of the complex nature of aneurismal flow. Endovascular devices present a rather dense and fine strut network, ...

Effect of Flow Diversion Treatment on Very Small Ruptured Aneurysms

Luca Augsburger, Daniel Ruefenacht

BACKGROUND: Ruptured aneurysms of < 2 mm are not amenable to endovascular coiling and therefore pose a significant treatment challenge. ...

Methodologies to assess blood flow in cerebral aneurysms: Current state of research and perspectives

Nikolaos Stergiopoulos, Mohamed Farhat, Philippe Reymond, Luca Augsburger, Edouard Fonck

With intracranial aneurysms disease bringing a weakened arterial wall segment to initiate, grow and potentially rupture an aneurysm, current understanding of vessel wall biology perceives the disease to follow the path of a dynamic evolution and increasing ...

Fluid mechanics of cerebral aneurysms and effects of intracranial stents on cerebral aneurysm flow

Luca Augsburger

This thesis focuses on intracranial aneurysms and particularly on the effect of blood flow in the three major phases that characterize an aneurysm: initiation, growth and rupture. As it stands today, blood flow is the major driver of this disease. The unde ...

Reproducibility of haemodynamical simulations in a subject-specific stented aneurysm model - A report on the Virtual Intracranial Stenting Challenge 2007

Philippe Reymond, Luca Augsburger, Daniel Ruefenacht

This paper presents the results of the Virtual Intracranial Stenting Challenge (VISC) 2007, an international initiative whose aim was to establish the reproducibility of state-of-the-art haemodynamical simulation techniques in subject-specific stented mode ...

Treatment of renal artery aneurysm with the multilayer stent

Luca Augsburger, Daniel Ruefenacht, Bastien Chopard, Isabelle Henry

Purpose: To describe a new type of stent consisting of a 3-dimensional (3D) braided tube made of 2 interconnected layers without any covering to treat a renal artery aneurysm. ...

Effect of elastin degradation on carotid wall mechanics as assessed by a constituent-based biomechanical model

Nikolaos Stergiopoulos, Sylvain Roy, Luca Augsburger, Edouard Fonck, Gilles Prod'Hom

Arteries display a nonlinear anisotropic behavior dictated by the elastic properties and structural arrangement of its main constituents, elastin, collagen, and vascular smooth muscle. Elastin provides for structural integrity and for the compliance of the ...
