Aneurysms can happen in any blood vessel, but they usually form in the belly or chest portions of your aorta -- the main blood vessel that carries blood from your heart -- or in arteries that nourish your brain. Aneurysms there are serious, while those in other areas, such as your leg, can be less hazardous.

Where are aneurysms most commonly found?
