Time course of flow-induced adaptation of carotid artery biomechanical properties, structure and zero-stress state in the arteriovenous shunt

Numerous studies have provided evidence of diameter adaptation secondary to flow-overload. but with ambiguous findings vis a vis other morphological parameters and information on the biomechanical aspects of arterial adaptation is rather incomplete. We exa ...

Continuous arterial spin labeling of mouse cerebral blood flow using an actively-detuned two-coil system at 9.4T

Rolf Gruetter, Hongxia Lei, Yves Pilloud

Among numerous magnetic resonance imaging (MRI) techniques, perfusion MRI provides insight into the passage of blood through the brain's vascular network non-invasively. Studying disease models and transgenic mice would intrinsically help understanding the ...

A method for the quantification of the pressure dependent 3D collagen configuration in the arterial adventitia

Nikolaos Stergiopoulos, Jelle Tymen Christiaan Schrauwen

Collagen plays an important role in the response of the arterial wall to mechanical loading and presumably has a load-bearing function preventing overdistension. Collagen configuration is important for understanding this role, in particular in mathematical ...

Reduction strategies for shape dependent inverse problems in haemodynamics

Gianluigi Rozza, Andrea Manzoni, Toni Mikael Lassila

This work deals with the development and application of reduction strategies for real-time and many query problems arising in fluid dynamics, such as shape optimization, shape registration (reconstruction), and shape parametrization. The proposed strategy ...

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 ...

Biomechanical, morphological and zero-stress state characterization of jugular vein remodeling in arteriovenous fistulas for hemodialysis

Nikolaos Stergiopoulos

While the role of hemodynamic variables on the development of intimal hyperplasia in arteriovenous fistulas for hemodialysis has been examined, less is known about the intramural biomechanical factors. In this study, arteriovenous fistulas were created by ...

Effect of aging on elastin functionality in human cerebral arteries

Michaël Unser, Nikolaos Stergiopoulos, Daniel Sage, Edouard Fonck, Jean Fasel

Aging affects elastin, a key component of the arterial wall integrity and functionality. Elastin degradation in cerebral vessels is associated with cerebrovascular disease. The goal of this study is to assess the biomechanical properties of human cerebral ...

Influence of inlet boundary conditions on the local haemodynamics of intracranial aneurysms

Nikolaos Stergiopoulos, Philippe Reymond

Haemodynamics is believed to play an important role in the initiation, growth and rupture of intracranial aneurysms. In this context, computational haemodynamics has been extensively used in an effort to establish correlations between flow variables and cl ...
