Testing for an abdominal aortic aneurysm (AAA) typically involves a physical examination, imaging tests, and an ultrasound scan.
A physical exam is usually the first step in diagnosing an abdominal aortic aneurysm. During the exam, your doctor will usually feel your abdomen and look for signs of an enlarged aorta. Your doctor may also check your blood pressure and listen to your heartbeat and lungs.
Imaging tests are often used to confirm the diagnosis of an AAA. A computed tomography (CT) scan or magnetic resonance imaging (MRI) scan can provide a detailed view of your aorta and other organs in the abdomen. These scans can help your doctor determine the size and shape of the aneurysm.
An ultrasound scan is also used to diagnose an AAA. This test uses sound waves to create an image of the aorta. The ultrasound can help your doctor determine the size and shape of the aneurysm, as well as any blood flow problems that may be present.
Your doctor may also order additional tests, such as an echocardiogram or angiogram, to help evaluate the aneurysm. An echocardiogram is a type of ultrasound that provides images of your heart, while an angiogram is an X-ray imaging test that can provide detailed images of the aorta and other blood vessels.
If an AAA is detected, your doctor will likely recommend treatment to prevent it from rupturing. Treatment options may include lifestyle changes, medications, or surgery. Your doctor will discuss the best treatment option for you based on your individual case.
