A new wall stress equation for aneurysm-rupture prediction.
Aneurysms, especially in the abdominal aorta (AAA), are prone to rupture, and hence a reliable and easy-to-use predictor is most desirable. Based on clinical observations and numerical analyses, a semi-empirical equation for the peak AAA-wall stress has been developed. It can be readily used for AAA-rupture predictions or can be integrated into more elaborate AAA-assessment models.
