Abstract

An aneurysm is the permanent localized dilation of an artery exceeding 50% of its expected normal size. Abdominal aortic aneurysm (AAA) is a degenerative vascular disease characterized by pathological enlargement of the abdominal aorta to 30 mm or more. AAA primarily affects men over the age of 65 and is often undiagnosed until it reaches a critical stage. The condition is usually asymptomatic until the sudden rupture of the aortic wall, a life-threatening event with a mortality rate exceeding 80%. Since the risk of rupture is directly linked to aneurysm size, non-invasive ultrasound examination is an effective tool for diagnosis and disease monitoring. Treatment strategies depend on aneurysm size, growth rate, overall patient age, health, and comorbidities. Management of smaller aneurysms focuses on risk factor control, including smoking cessation and pharmacological treatment. Larger, symptomatic, or ruptured aneurysms require open surgical repair or endovascular aneurysm repair. EVAR is a preferred approach for anatomically suitable and high-risk elderly patients. Early detection through screening programs plays a crucial role in monitoring disease progression and preventing rupture, ultimately reducing AAA-related mortality.
