Overview

Aging, atherosclerosis, diabetes, hypertension and trauma are common risk factors for aortic dissection.

Risk Factors

• Aging
• Atherosclerosis and its associated risk factors like diabetes
• Bicuspid aortic valve is the next most common risk factor, seen in approximately 7%.
• Cocaine abuse
• Coarctation of the aorta
• Cystic medial necrosis
• Deceleration trauma most commonly causes aortic rupture, not dissection.
• Ehlers-Danlos syndrome
• Giant cell arteritis
• Hypertension is seen in 71-86% of patients, occurring most frequently in those with type III dissection.
• Marfan’s syndrome was seen in 6%.
• Turner's syndrome
• Tertiary syphilis
• Third trimester of pregnancy
