Abdominal aortic aneurysm
| Ectatic or mild dilatation |
>2.0 cm and <3.0 cm[1] |
| Moderate | 3.0 - 5.0[1] (or 5.5)[2] cm |
| Large or severe | >5.0[1] or 5.5[2] cm |
Abdominal aortic aneurysms are commonly divided according to their size and symptomatology. An aneurysm is usually defined as an outer aortic diameter over 3 cm (normal diameter of the aorta is around 2 cm),[3] or more than 50% of normal diameter.[4] The suprarenal aorta normally measures about 0.5 cm larger than the infrarenal aorta.[5]
Common iliac artery aneurysm
| Normal | Diameter ≤12 mm |
| Ectasia | Diameter 12 to 18 mm |
| Aneurysm | Diameter ≥18 mm |
