Sažetak
Abdominal aortic aneurysms (AAAs) are localized dilatations of the infrarenal aorta that typically harbor intraluminal thrombi (ILTs). These thrombi can either disrupt the wall biochemically or shield it mechanically. AAAs often remain asymptomatic until rupture, an event with high mortality rate. Current clinical capabilities for predicting 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. 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.
