Question: are aneurysms measured in cm or mm?
Answer: Given that the average abdominal aorta measures 2 cm, an abdominal aortic aneurysm (AAA) is defined by a measurement of 3 cm (30 mm) or greater. The prevalence of AAA increases with age; also, it is higher in males and in those with a smoking history, atherosclerotic disease and family history.
