Abdominal aortic aneurysm involves dilation of which vessel?

Abdominal aortic aneurysm involves dilation of which vessel?

• A. Abdominal Aorta
• B. Inferior Vena Cava
• C. Superior Mesenteric Artery
• D. Renal Artery

Answer: (A)

An abdominal aortic aneurysm involves dilation of the abdominal aorta, the large artery that runs through the abdomen. An aneurysm is a localized widening of a vessel wall, typically due to weakening from factors like atherosclerosis and aging. This distinguishes it from dilation of the inferior vena cava, which is a vein, or dilation of other arteries such as the superior mesenteric or renal arteries. So the vessel involved is the abdominal aorta.
