Aortic Aneurysm - Causes and Risk Factors

​Causes of aortic aneurysms

While the exact cause of aortic aneurysms is unknown, ageing and chronic health conditions can lead to a weakening of the aortic wall, which can then bulge under the pressure of blood flowing through the aorta. 

These chronic conditions include: 

Risk factors of aortic aneurysm

An aortic aneurysm usually occurs in: 
  • The middle-aged and elderly, of around aged 50 and above
  • Smokers bear a significantly higher risk

Screening for abdominal aortic aneurysms is recommended for current or past male smokers over the age of 65.

Congenital conditions, such as Marfan’s syndrome and bicuspid aortic valves, may also weaken aortic walls, diminishing their ability to withstand the sheer forces of blood flowing through them.
