Abdominal aortic aneurysm (AAA) is a pathological condition characterised by localised dilation of the infrarenal aorta, which can be fatal if rupture occurs. Current diagnostic criteria for repair are not patient-specific, but computational modelling may help to predict potential growth and risk AAA accurately. This paper highlights how important using Windkessel effect fully-developed inflow velocity framework biomechanical analysis is; in other words, this research investigates different...
Abstract Aortic dissection is a life‐threatening condition with rising prevalence in the elderly population, possibly as consequence of increasing population life expectancy. Untreated aortic can lead to myocardial infarction, branch malperfusion or occlusion, rupture, aneurysm formation and death. This study aims assess potential biomechanical model predicting risks non‐dilated thoracic aorta Stanford type A dissection. To achieve this, fully coupled fluid–structure interaction was...
ABSTRACT Reported in this paper is a cutting‐edge computational investigation into the influence of geometric characteristics on abdominal aortic aneurysm (AAA) rupture risk, beyond traditional measure maximum diameter. A Comprehensive fluid–structure interaction (FSI) analysis was employed to assess risk factors range patient scenarios, with use three‐dimensional (3D) AAA models reconstructed from patient‐specific data and finite element method. Wall shear stress (WSS), its derivatives such...
Abdominal aortic aneurysm (AAA) rupture has become a prevalent cause of death and is responsible for approximately 200,000 deaths annually worldwide. Due to the fact that abdominal aneurysms are permanent progressive dilatations asymptomatic until rupture, there rising need study characteristics mechanics disease so it can be recognised earlier on, thus preventing patients from risks. This paper analyses relationship between nonlinear material hyperelasticity variability presence...
The current clinical index for surgical intervention of abdominal aortic aneurysms (AAA) is mainly based on measuring its maximum diameter. However, ruptures in AAAs do not necessarily occur at this location and conditions rupture are still unclear. This study focuses the understanding mechanisms. A set fluid-structure interaction (FSI) models developed to investigate expansion into low wall shear stress (WSS) regions. 3D model geometries different stages acquired from literature including...
