Improving the efficiency of abdominal aortic aneurysm wall stress computations

Abdominal aortic aneurysm (AAA) rupture risk is traditionally assessed by maximal diameter, but wall stress offers a more accurate predictor. This study proposes a simplified linear modeling approach to estimate patient-specific wall stresses efficiently, eliminating the computational burden of nonlinear methods. Results from idealized and patient-specific simulations show the linear model closely approximates reference stresses, suggesting its potential as a practical clinical tool for identifying high-risk AAAs.
