Why the study?
Diameter-based thresholds for planned repair of abdominal aortic aneurysms are empirical and fail to reliably predict rupture, requiring better knowledge of vessel wall micromechanical and ultrastructural properties to improve risk prediction.

May enhance AAA rupture stratification in research; leaves open clinical adoption pending validation.
Understanding the micromechanical and ultrastructural properties of abdominal aortic aneurysms using high-resolution techniques may improve personalized rupture risk prediction compared to current empirical diameter thresholds.
Hossack et al. (2022) conducted a review in Abdominal Aortic Aneurysms. High-resolution engineering techniques such as nanoindentation and atomic force microscopy can measure the micromechanical properties of abdominal aortic tissue to improve rupture risk prediction.
