  This study focuses on the impact of geometric factors such as asymmetry, irregularity and tortuosity on the progression and rupture of Abdominal Aortic Aneurysms (AAA). The current surgical threshold based on maximum transverse diameter lacks precision, underlining the importance of understanding the aneurysmal wall's intrinsic biomechanical properties through destructive testing. We aimed to determine the influence of AAA morphology on its wall biomechanics by correlating preoperative tomographic geometries with uniaxial biomechanical test data of arterial fragments from open aneurysm repair. It’s an observational experimental and multicenter study, 47 individuals with AAA undergoing open repair had an anterior wall fragment tested uniaxially for load, stress, tension, strain energy, strain and thickness. Preoperative CT scans yielded 26 geometric indices, analyzed statisti.. View more»
