Rupture behaviour of abdominal aortic aneurysms: an experimental and computational investigation
Author(s) :
Doyle, Barry J.
Description :
non-peer-reviewed
,
Abdominal aortic aneurysm (AAAs) is a permanent and irreversible dilation of the infrarenal section of the aorta. These aneurysms are typically defined as having a diameter 50% greater than the normal aortic diameter. If left untreated, AAAs will continually expand until rupture, wi...

A comparison of modelling techniques for computing wall stress in abdominal aortic aneurysms
Description :
BACKGROUND: Aneurysms, in particular abdominal aortic aneurysms (AAA), form a significant portion of cardiovascular related deaths. There is much debate as to the most suitable tool for rupture prediction and interventional surgery of AAAs, and currently maximum diameter is used clinically as the de...

Towards an improvement in aneurysm assessment: coupling 3D reconstruction tools with engineering know-how
Description :
Purpose: Currently, abdominal aortic aneurysms (AAAs), which are a permanent dilation of the aorta, are treated surgically when the maximum transverse diameter surpasses 5.0cm. AAA rupture occurs when the locally acting wall stress exceeds the locally acting wall strength. There is a need to review ...

New approaches to abdominal aortic aneurysm rupture risk assessment - engineering insights with clinical gain
Description :
Abdominal aortic aneurysm (AAA) rupture remains a significant cause of death in the developed world. Current treatment approaches rely heavily on the size of the aneurysm to decide on the most appropriate time for clinical intervention and treatment. However, over recent years several alternative ...

Description :
Currently, abdominal aortic aneurysms (AAAs), which are a permanent dilation of the aorta, are treated surgically when the maximum transverse diameter surpasses 5.5cm. AAA rupture occurs when the locally acting wall stress exceeds the locally acting wall strength. There is a need to review the curre...

Description :
In the event of abdominal aortic aneurysm (AAA) rupture, the outcome is often death. This paper aims to experimentally identify the rupture locations of in vitro AAA models and validate these rupture sites using finite element analysis (FEA). Silicone rubber AAA models were manufactured using two ...

Description :
This paper aims to identify the rupture locations of abdominal aortic aneurysms. Dow Corning Sylgard 184 was mechanically characterised. Five idealised models were then manufactured using this silicone rubber which were subsequently inflated to rupture with the images recorded using a high speed cam...

Description :
A range of silicone rubbers were created based on existing commercially available materials. These silicones were designed to be visually different from one another and have distinct material properties, in particular, ultimate tensile strengths and tear strengths. In total, eleven silicone rubbers ...
