Impact of backbone on stresses in abdominal aortic aneurysms

Impact of backbone on stresses in abdominal aortic aneurysms

Abstrakt

Computational modelling of stress-strain states in Abdominal Aortic Aneurysms (AAAs) has become an important tool in assessment of their rupture risk in the last decades. Its possibility to be used in the clinical practice is increasing with every influencing factor considered in the model. Very little attention has been devoted to the impact of the surrounding tissue. AAA is surrounded by less or more compliant connections with other organs along its length. Backbone is rather stiffer than the other surrounded tissue and there are several contacts with the AAA. The AAA may be bended over the backbone which induces additional bending stresses in it.
