What is a visceral artery aneurysm?

An aneurysm is a bulging or ballooning in the wall of a blood vessel. It is caused when a portion of the artery wall weakens. As the aneurysm expands (like a balloon), the artery wall grows progressively thinner, increasing the likelihood that the aneurysm will burst.

Peripheral aneurysms affect arteries other than the aorta. A visceral artery aneurysm is a peripheral aneurysm found in the arteries feeding the kidneys, intestines or other intra-abdominal organs.
