What term describes a dilatation of the Aorta equal to or exceeding 3 cm in diameter?

What term describes a dilatation of the Aorta equal to or exceeding 3 cm in diameter?

• A. AAA
• B. Ectatic aneurysm
• C. Fusiform Aneurysm
• D. Mycotic Aneurysm

Answer: (A)

An aneurysm is a dilation of an artery. When the abdominal aorta enlarges to 3 cm or more in diameter, the condition is called an abdominal aortic aneurysm. The 3 cm threshold is the standard size criterion used to define an aneurysm in the abdomen. The other terms describe different ideas: ectatic dilation refers to a mild, generalized widening; a fusiform aneurysm describes the shape of the dilation (spindle-shaped) but not the size criterion by itself; a mycotic aneurysm is an infection-related aneurysm. So the label that matches a dilation of the aorta equal to or exceeding 3 cm is an abdominal aortic aneurysm.
