The exact causes of thoracic aortic aneurysms are unknown, but factors that can contribute to an aneurysm's development include:


 * Marfan syndrome
 * Genetic condition
 * affects connective tissue
 * weakness in aortic wall increases susceptibility of an aneurysm
 * distinct physical traits- tall stature, very long arms, eye problems, and a deformed breastbone


 * Other connective tissue diseases
 * Ehlers-Danlos syndrome-causes skin and joints to be fragile and makes your skin stretch easily


 * Heart valve complications- aortic valve complications, such as a bicuspid aortic valve
 * Previous injury to the aorta such as an aortic dissection
 * Traumatic injury
