These aneurysms typically grow slowly, but the risk of rupture and compression increase with the size. | Aortic aneurysms are problematic because they can rupture, which kills most of affected people within minutes or hours, and because they can compress other structures.

<noinclude>[[Category:Vascular surgery]] | Degeneration of elastic and collagen fibres, as well as [[atherosclerosis]], causes the formation of the aneurysm. Degeneration occurs due to mechanical stress due to [[hypertension]] and due to activation of proteases like [[collagenase]], [[elastase]], [[matrix metalloproteinase]], and [[plasmin]].<noinclude>[[Category:Vascular surgery]] | ||
