What is the weakening and resulting local dilation of the wall of an artery called?

The weakening and resulting local dilation of the wall of an artery is called an aneurysm. This condition occurs when the arterial wall becomes thin and bulges due to increased pressure or damage, potentially leading to serious complications if it ruptures. Aneurysms can occur in various parts of the body, including the aorta, brain, and legs. Regular monitoring and, in some cases, surgical intervention may be necessary to manage the condition.
