Detailed explanation-1: -What is an aneurysm? An aneurysm is a bulging, weakened area in the wall of a blood vessel resulting in an abnormal widening or ballooning greater than 50% of the vessel’s normal diameter (width). An aneurysm may occur in any blood vessel, but is most often seen in an artery rather than a vein.

Detailed explanation-2: -An aneurysm is a bulge in a blood vessel caused by a weakness in the blood vessel wall, usually where it branches. As blood passes through the weakened blood vessel, the blood pressure causes a small area to bulge outwards like a balloon.

Detailed explanation-3: -An aneurysm-a balloon-like bulge in an artery-can develop and grow for years without causing any symptoms.
