Article Synopsis
- This study explores how the degree of graft oversizing in endovascular aneurysm repair (EVAR) affects the strain in the seal zone of abdominal aortic aneurysms, suggesting that excessive strain reduction may negatively impact the aneurysm neck.
- The researchers conducted experiments using different types of endografts and assessed strain changes with ultrasound elastography, comparing three oversizing levels: 20%, 30%, and 50%.
- Results indicated significant differences in strain reduction when comparing normal (empty) phantoms to those with oversizing, highlighting the potential risks associated with high graft oversizing.
Introduction: Current abdominal aortic aneurysm (AAA) assessment relies on analysis of AAA diameter and growth rate. However, evidence demonstrates that AAA pathology varies among patients and morphometric analysis alone is insufficient to precisely predict individual rupture risk. Biomechanical parameters, such as pressure-normalized AAA principal wall strain (/PP, %/mmHg), can provide useful information for AAA assessment.

However, in the absence of regression, morphometric analysis alone is insufficient to reliably predict the successful remodeling of AAAs after EVAR. Biomechanical parameters, such as pressure-normalized principal strain, might provide useful information in the post-EVAR AAA assessment.
