An aneurysm is a localised dilatation/ballooning/swelling of any blood vessel. Generally, the majority of aneurysms are thought to be due to a degenerative inflammatory process that affects the strength of the aortic wall.Generic factor such as Marfan and Ehlers-Danlos syndromes are risk factors. The operative treatment of aortic aneurysms aims to prevent the aneurysm from rupture and thereby improving the life expectancy of the patient.
