Background

Aneurysmal disease spans abdominal ([[abdominal aortic aneurysm (AAA)]]), thoracic ([[TAA]]), thoracoabdominal ([[TAAA]]), and peripheral arterial beds [@esc2014] and remains a leading cause of sudden vascular death due to rupture. AAA prevalence in men ≥65 years is approximately 1.5–4.5% [@wanhainen2019][@esvs2024-editors] and lower in women, who have higher rupture risk at smaller diameters [@svs2018]. Thoracic aneurysms are less common but carry high lethality, particularly in connective tissue disorders (Marfan, Loeys–Dietz, vascular Ehlers–Danlos) [@esc2014]. Peripheral aneurysms (popliteal, femoral, visceral, renal) often coexist with AAA [@dawson1997]. Population screening of older men reduces AAA-related mortality and emergent repairs, and contemporary guidelines define who to screen and how to surveil detected AAAs [@mass2002] [@svs2018] [@esc2014].[@esc2014] [@esvs2024-editors].
