Causes of Abdominal Aortic Aneurysm

Abdominal Aortic Aneurysm does not have any well defined cause. Additionally the severity of abdominal aortic aneurysm depends on size of aneurysm; larger aneurysms are at greater risk of breakage. This condition usually caused due to artery wall weakness. Exact reason behind this weakness of artery walls is not well known. However, there can be some triggering factors which can lead to this condition like:

  • Smokers are at greater risk
  • Hypertension causes artery wall weakness and ultimately AAA
  • Males are at greater risk for catching such condition
  • Genetic factors are also involved sometimes.

  • CT scan of abdominal area that will tell about aneurysm size
  • Abdominal ultrasound to check aneurysm presence
  • Computed Tomography angiogram (CTA) before surgery

These tests will help for proper diagnosis of Abdominal Aortic Aneurysm

Management of Abdominal Aortic Aneurysm

If the aneurysm is small like less than 2 inches, surgery won’t be done instead preferred management would be done via medication while for the aneurysms greater than 2 inches, best treatment is surgery.

In case of larger of ballooned aorta, breakage or tearing of aneurysm occur and cause bleeding inside body. In such condition patient would be immediately referred for surgery. Open repair surgery or endovascular stent grafting surgery are mostly done. In the former, large cuts are done in the abdomen area while in later large cuts are not needed and recovery rate is quick. Surgery if done before rupture is best way to avoid complications.
