a. Smoking
b. Hypertension
c. Cystic medial necrosis
d. Type 2 diabetes mellitus
e. Presence of FBN 1 gene

Correct Answer is B


The most common cause of aneurysm formation is atherosclerosis, primarily related to hypertension. Marfan syndrome is a significant risk factor for aneurysm formation and dissection, and therefore the threshold for treating these aneurysms is lower than in the non-Marfan population.
