Final answer:
Cystic medial necrosis of the aorta is primarily associated with Marfan syndrome, a genetic disorder that negatively impacts connective tissues leading to aortic wall weakening. It is a different condition from atherosclerosis and not directly associated with hypertension or Ehlers-Danlos syndrome. The correct option is D.
Step-by-step explanation:
Cystic medial necrosis of the aorta is associated with Marfan syndrome. Marfan syndrome is a genetic disorder that affects connective tissue and can lead to severe cardiovascular issues including abnormalities in the aorta, such as cystic medial necrosis.
This condition involves the degeneration of the elastic fibers in the media of the aorta, leading to the weakening of the aortic wall. In contrast, atherosclerosis, which is characterized by the deposition of cholesterylesters and other lipids in the connective tissues of the arterial walls, is a different condition.
Hypertension can contribute to aortic disease but is not directly associated with cystic medial necrosis. Ehlers-Danlos syndrome, another connective tissue disorder, can affect the aorta but does not typically present with cystic medial degeneration as a primary feature. The correct option is D.
