Thoracic aortic aneurysms can cause aortic dissection (splitting of the aortic wall) and aortic rupture, leading to life-threatening internal bleeding. Mortality rates of 80% have been reported with these lesions. The two principal causes for this type of aneurysm are dissection and atherosclerosis; disorders of collagen and elastin metabolism, by infections, very rarely by neoplastic invasion of the arterial wall and also iatrogenesis are other origins for this vasculopathy.
