The ballooning out of an artery wall at a point where it has been weakened by deterioration is?

The ballooning out of an artery wall at a weakened point is known as an aneurysm. This condition occurs when the structural integrity of the arterial wall deteriorates, often due to factors like high blood pressure, atherosclerosis, or genetic predispositions. If left untreated, an aneurysm can rupture, leading to serious complications, including life-threatening internal bleeding. Regular monitoring and, in some cases, surgical intervention may be necessary to manage this condition.
