Abdominal Aortic Aneurysm

Abdominal Aortic Aneurysm (AAA) kills more than 10,000 Americans annually. It ranks in the "top 10" causes of death in the over-55 population. This deadly disease develops when the large artery carrying blood from the heart through the abdomen becomes enlarged as a result of fatty plaque buildup or other blockage. The artery wall, much like a balloon, becomes thinner and weaker as it expands. The enlarged artery has a high risk of rupture without warning.

Once considered a sure fatal disease, AAA can now be successfully treated. Early detection helps to ensure that the aneurysm is found in the earliest stage of development, allowing the opportunity for repair while it is small. Given the high death rate from ruptured aneurysm and the low risk of elective surgery, the logic for screening is clear.

A baseline ultrasound test is recommended for high-risk patients: over 55, male, family history of AAA, arteriosclerosis, smoker, and high blood pressure. Ultrasound creates images of the artery and provides a safe and relatively inexpensive, noninvasive confirming test. If an aneurysm is found when it is small, there is a better chance of a successful repair as well as a full recovery.
