VILALTA-ALONSO, Guillermo et al. Rupture of abdominal aortic aneurysm. Software for its prediction. Ingeniería Mecánica [online]. 2011, vol.14, n.1, pp.52-64. ISSN 1815-5944.

The rupture of abdominal aortic aneurysm (AAA) represents an important clinical event due to its high mortality rate. Currently the criteria to decide on the treatment of AAA patients are the peak transverse diameter and the growth rate which can be considered insufficient because they have not a reasonable physical base. The foundations for the design of PC software to predict, with sufficient accuracy to be clinically relevant, the risk of AAA rupture on patient-specific basis are defined in this paper. The software consists of 3 modules which are designed for processing all patient-specific information and integrate them through a model that interrelates the different nature (biological, structural and geometric) and scales (temporal and dimensional) biomechanical factors, in order to calculate a numerical and patient-specific indicator of the rupture risk. This tool should be an auxiliary element to physician in making decision on appropriate treatment decisions for patients with aneurysm.

Keywords : AAA; rupture risk; multiscale model; prediction; computer tool.
