In an asymptomatic abdominal aoa aneurysm, elective repair is indicated if the aneurysmal diameter is greater than: (A) 5.5 cm, (B) 6.5 cm, (C) 7.5 cm, (D) 8.5 cm
Answer is A. An asymptomatic abdominal aoic aneurysm in an otherwise fit patient should be considered for repair if >55 mm in diameter (measured by ultrasonography). The annual incidence of rupture rises from 1% or less in aneurysms that are <55 mm in diameter to a significant level, perhaps as high as 25%, in those that are 70 mm in diameter.Ref: Bailey and love pg: 961
