What is the typical age range for abdominal aortic aneurysm (AAA)?

• A. 20-40
• B. 40-70
• C. 60-80
• D. 30-60

Answer: (B)

Abdominal aortic aneurysm is most common in older adults, as the aortic wall weakens with age and atherosclerotic changes accumulate over time. In clinical practice you see most new or diagnosed AAAs beginning in middle age and continuing into older adulthood. Among the given options, the range that best captures when AAA is typically encountered is forty to seventy years. This span reflects the period when incidence starts to rise and remains appreciable for a large portion of adulthood. While there are cases outside this window, and AAA can present in older individuals, this range best aligns with how the condition most often presents in the population.
