While definite genetic abnormalities were identified in true genetic syndromes Marfan, Elher-Danlos and others associated with aortic aneurysms, both thoracic and abdominal aortic aneurysms demonstrate a strong genetic component in their aetiology.

They are most commonly located in the abdominal aortabut can also be located in the thoracic aorta. This does not treat the aortic aneurysm per se, but control of hypertension within tight blood pressure parameters may decrease the rate of expansion of the aneurysm.
