Soto B, et al. - Researchers here assessed the association between peak wall stress (PWS) and maximum diameter (MD) with symptoms of abdominal aortic aneurysm (AAA). Compared to asymptomatic AAA patients (aAAA), symptomatic AAA (sAAA) patients indicated greater MD and biomechanical parameters. However, when AAA patients with MD ≥ 65 mm were considered separately, the MD was unable to recognise sAAA, while PWS, and particularly diameter normalised PWS (dnPWS), were able to do so.
