Final answer:
Marfan's syndrome is a genetic disorder that affects connective tissue and is a possible etiology for aortic aneurysms due to abnormal fibrillin affecting the aortic wall. While other cardiovascular issues can be associated with the aorta, Marfan's syndrome has a direct correlation with aneurysm risks.
Step-by-step explanation:
Aortic Aneurysm and its Etiologies
A possible etiology for an aortic aneurysm is Marfan's syndrome. Marfan's syndrome is a genetic disorder that affects the body's connective tissue, which includes the walls of the aorta. People with Marfan's syndrome have abnormal fibrillin, which can weaken the aortic wall and lead to aneurysm formation. Other causes such as atherosclerosis and high blood pressure can also lead to aneurysms, but they are not the direct causes mentioned in the multiple-choice options.
Aortic aneurysms can have devastating consequences if they rupture, leading to severe hemorrhage and potentially death. Marfan syndrome is particularly known for its association with vascular abnormalities, including the deterioration of the aorta, which directly relates to the risk of developing aortic aneurysms.
It is important to note that while conditions like aortic insufficiency, coronary artery disease, and dilated cardiomyopathy are related to the cardiovascular system, they do not directly cause aortic aneurysms, hence making Marfan's syndrome the correct answer.
