Abdominal Aortic Aneurysm

Abdominal aortic aneurysms (AAA) often grow slowly and are usually asymptomatic. AAA is usually detected incidentally during a scan performed for another reason. It is difficult to establish their prevalence.
 

Management of an AAA depends primarily on its size. Small and medium aneurysms (aortal diameters of 3–4.4 cm and 4.5–5.4 cm) are managed conservatively. When the aorta reaches a diameter of 5.5 cm (large aneurysm), a person is referred to a vascular surgeon.
