An abdominal aortic aneurysm (AAA) is a condition in which the abdominal aorta, the main blood artery that carries oxygenated blood to the lower body, abnormally enlarges and becomes a tubular form. The abdominal aorta has consistently and uniformly dilated over its whole length, as shown by the tubular appearance.


  • Many AAA patients may not exhibit any symptoms, especially in the beginning.
  • Some patients may experience a pulsating sensation in their stomach as the aneurysm enlarges.
  • A ruptured AAA or severe instances may result in abrupt, severe abdomen or back pain, which can be a medical emergency.
  • Dizziness, a fast pulse, low blood pressure, and loss of consciousness are other signs of a ruptured AAA.


  • Although the precise etiology of AAA is not completely understood, it is thought to be a result of both hereditary and environmental factors.
  • Atherosclerosis (hardening of the arteries) and other connective tissue diseases, such as Marfan syndrome or Ehlers-Danlos syndrome, are major risk factors. Other risk factors include advanced age, male gender (more prevalent in males), smoking cigarettes, and high blood pressure.

Potential Complications:

  • Rupture: The most severe AAA consequence, a rupture can result in extensive internal bleeding and be potentially fatal.
  • Dissection: Aortic dissection, a disorder caused by a tear in the aorta’s inner lining, can arise from AAA.
  • Thrombus or embolism: Aneurysms can develop blood clots that can break free. Spread to other areas of the body, blocking smaller blood arteries.
  • Compression: An enlarged AAA may occasionally put pressure on adjacent organs or tissues, resulting in pain or discomfort.

Tests for diagnosis purpose:

  • Ultrasound: This non-invasive imaging method is frequently used to identify AAA. It can assess the size of the aneurysm and uses sound waves to see the abdominal aorta.
  • Computed Tomography (CT) Scan: CT scans offer fine-grained cross-sectional views of the abdominal aorta. That enable accurate evaluation of the aneurysm’s size, location, and potential consequences.
  • Magnetic Resonance Imaging (MRI): Like CT scans, MRIs are able to create precise pictures of the abdominal aorta that reveal details about the aneurysm’s features.
  • Angiography: To see the blood flow and find anomalies in the abdominal aorta, a contrast dye may occasionally be injected into the blood arteries. X-ray pictures are then captured.

The size and growing rate of the aneurysm, as well as the patient’s general health, are a few of the variables that affect treatment options and management of AAA. The management of AAA and avoiding complications depend on routine monitoring, lifestyle changes, and medical intervention.
