Final answer:
An abnormal, blood-filled dilation of a blood vessel wall seen in older patients is called an aneurysm, often resulting from atherosclerosis. Risk factors include lifestyle and genetic factors, while treatments range from lifestyle changes to surgical interventions such as angioplasty.
Step-by-step explanation:
An abnormal, blood-filled dilation of the wall of a blood vessel that is commonly seen in geriatric patients is called an aneurysm. This condition can be a result of atherosclerosis, which is the buildup of fatty plaques in the arteries. Over time, these plaques can cause the arterial walls to weaken and potentially lead to dilation or even rupture. Risk factors for atherosclerosis, which can contribute to aneurysm formation, include smoking, hypertension, obesity, diabetes, high alcohol consumption, lack of exercise, stress, and high levels of lipids in the blood (hyperlipidemia). Treatments for atherosclerosis and its complications may include lifestyle changes, such as diet and exercise; medical interventions like medication, angioplasty with a balloon catheter, stent insertion, or coronary bypass procedure; and careful management of underlying conditions that might exacerbate the issue, like heart failure or liver cirrhosis leading to hypervolemia.
