Aortic Aneurysm: What Patients Should Know

What an aortic aneurysm is, how it is found, and how monitoring works.


An aortic aneurysm is a localized enlargement of the largest blood vessel in the body. It usually causes no symptoms and is found incidentally.

Small aneurysms are followed with periodic imaging. When an aneurysm is larger or grows quickly, endovascular or open treatment is considered.

The decision to treat is made individually, based on size, growth rate, and overall condition.
