Complications of Abdominal Aortic Aneurism

It is important to understand complications of abdominal aortic aneurism as this will make a strong case for abdominal aortic aneurysm screening participation.

Complications of undetected / lately detected and untreated abdominal aortic aneurysm are potentially fatal. Common complications of abdominal aortic aneurism are seen once the aneurysm gets wider than 4.0 cm in diameter.

These complications are less likely in women, blacks, and diabetics.

Frequently reported complications of abdominal aortic aneurism include:

Chronic Back pain

One not uncommon presentation of abdominal aortic aneurysm is the development of a nagging back pain. Usually, this starts off as a central abdominal pain , and as time goes on, a central to lower back pain develops.

The pain is usually present all day long, and not associated with work or movement. It is caused by the increased size of the aorta pressing upon the back muscles and bones. A visit to your family doctor will be a valuable first step needed to identify if a chronic back pain is due to a possible abdominal aortic aneurysm. This complication of abdominal aortic aneurism alone could be an indication for repair of an aneurysm.


Ruptured abdominal aortic aneurism is the most frightening of complications of abdominal aortic aneurism. It is almost always fatal. Go to the section on ruptured abdominal aneurism and read more about it

Blood Clots

The excessive space in the lumen of an aneurysm causes a turbulent blood flow. This is a perfect condition for blood clots to form in the aorta. These clots could be of significantly large size. Should they migrate up to smaller arteries, they could block the lumen of the small artery totally. This would cause sudden loss of blood supply to that region. If this should happen in one of the arteries of the limbs, it can cause sudden death of the limb, preceded by sever pain, cold, loss of sensation in the limb and if within six hours steps are not taken to remove the clot, total loss of the limb or that body region can occur. This is a common but often not thought of as one of the frequent complications of abdominal aortic aneurism

Other complications of abdominal aortic aneurism are:


Heart failure


Kidney failure
