Regular ultrasound examination of asymptomatic patients with small abdominal aortic aneurysms is essential to document aneurysm growth and decide when intervention is warranted. The interval between examinations is dictated by the size of the aneurysm and its expected growth rate. Too frequent examinations can cause undue patient anxiety and are not cost effective.
Conditions: Abdominal Aortic Aneurysm (AAA)
