Aneurysm, abdominal aortic

Abdominal aortic aneurysm, an abnormal dilation in the arterial wall, most commonly occurs in the aorta between the renal arteries and iliac branches. More than 50% of patients with untreated abdominal aneurysms 6 cm or larger die within 2 years of diagnosis, primarily from aneurysmal rupture. More than 85% of patients with large aneurysms die within 5 years.

What causes it

Aneurysms commonly result from atherosclerosis, which weakens the aortic wall and gradually distends the lumen. Other causes include:

  • Fungal infection (mycotic aneurysms) of the aortic arch and descending segments
  • Congenital disorders, such as coarctation of the aorta, Marfan syndrome, and collagen vascular disorders
  • Trauma
  • Syphilis
  • Hypertension.
