What does a bulging of an aneurysm indicate?

A bulging of an aneurysm indicates a weakness of the vessel wall. An aneurysm forms when a section of a blood vessel becomes weakened, causing it to dilate or bulge under the pressure of blood flow. This structural weakness can result from various factors, including hypertension, atherosclerosis, or genetic predispositions.

As blood continues to flow through the vessel, the area that has weakened cannot withstand the normal pressure, leading to the characteristic bulging associated with an aneurysm. If the bulging progresses without intervention, it can lead to rupture, which poses significant health risks.
