Abdominal Aortic Aneurysm (AAA)

AAA stands for Abdominal Aortic Aneurysm. An abdominal aortic aneurysm is a potentially life-threatening condition in which the aorta–the large artery (blood vessel) that distributes blood to the organs of the body–enlarges or develops a bulge at the level of the abdomen. As this is the main pipe coming out of the heart, problems anywhere along its course can cause serious problems in the body.

One of the more common problems associated with AAA is that of aneurysmal degeneration. Aneurysms may result in the wall of the aorta weakening over time and, as it bulges or enlarges, the aorta’s wall thins out. This swelling makes it become even weaker and puts the aorta at risk of rupture. AAA is fairly common, especially in older men. This condition often shows no symptoms until later, but certain factors may put you at greater risk of developing an abdominal aortic aneurysm, including:

• Smoking (though cutting out smoking may reduce the speed at which an aneurysm grows)
• Atherosclerosis–a condition in which plaque builds up in the blood vessels, hindering adequate blood flow
• High blood pressure
• Physical trauma/injury

As a renowned cardiovascular surgeon in Houston, Dr. Davis has extensive experience in treating a wide variety of aortic disorders–and has done so with great success. Modern techniques have vastly reduced the risk associated with correcting these conditions, but not all patients get themselves tested. Testing is imperative in order to give patients a better prognosis that may allow them to be treated under non-emergent situations. The straightforward, noninvasive tests–such as vascular ultrasound–allow for patients to be identified early and monitored until they are deemed to be at risk of complications occurring. It’s important to note that a small AAA may be monitored for an extended period of time and may never grow beyond a certain point or result in rupture. However, if it has grown too quickly and/or to a certain size, surgical intervention may be required in order to prevent a rupture. By closely monitoring our patients, we can gain valuable insight into the best course of action and so you can regain your livelihood.
