Sažetak
Abdominal aortic aneurysms (AAAs) often remain asymptomatic until rupture, an event with high mortality rate. Clinical capabilities for predicting accurately the risk of rupture remain wanting, and clinical interventions continue to be based primarily on the maximum diameter or expansion rate of the lesion. Additionally, the majority of available clinical and experimental data focuses solely on radial changes and AAA maximum diameter, whereas changes in length, microstructure in axial direction, and axial growth rate have not been investigated. It is possible that this could lead to the incorrect conclusion that aneurysm is stable in case the maximum diameter does not change, while an aneurysm could still grow in axial direction. Therefore, in this contribution we study the importance of aneurysm length and axial growth rate on the rate of radial AAA expansion, and possibly rupture.
