An existing abdominal aorta aneurysm that involves the entire abdominal aorta is described as what?

• A. Ectactic aneurysm
• B. Abdominal aortic aneurysm
• C. Fusiform aneurysm
• D. Saccular aneurysm

Answer: (A)

Diffuse, long-length dilation of an artery along its entire course is described as ectasia. When the abdominal aorta is enlarged along the whole length rather than forming a single localized bulge, it fits the idea of an ectactic aneurysm. This emphasizes the difference from a focal outpouching (saccular) and from a segmental, shape-based description (fusiform) that can refer to a dilated segment but isn’t defined by involvement of the entire vessel. So describing the entire abdominal aorta as an ectactic aneurysm captures the notion of vessel-wide dilation rather than a localized bulge.
