What is an aneurysm?

The term aneurysm refers to any localized widening or outpouching of an artery, a vein, or the heart. Depending on their size and location, aneurysms may or may not produce symptoms. All aneurysms are potentially dangerous since the wall of the widened (dilated) portion of the involved vessel can become weakened and may possibly rupture.

Doctors refer to aneurysms by their anatomic location in the body, such as a thoracic aortic aneurysm, renal artery aneurysm, abdominal aortic aneurysm, heart ventricle aneurysm, etc.
