causes of aortic aneurysm
Aortic Aneurysm Causes, Symptoms and Concerns. UW Health heart surgeons have substantial expertise in the evaluation, diagnosis and treatment of aortic aneurysms. Up to 80 percent of aortic aneurysms are caused by hardening of the arteries (atherosclerosis). Atherosclerosis can develop when cholesterol and fat build up inside the arteries. High blood pressure (hypertension), cigarette smoking, family history and age also contribute to atherosclerosis.
