The most common exam finding for someone with an abdominal aortic aneurysm is an enlargement of the aorta, the body’s main artery. The aneurysm can be detected with a physical exam, ultrasound, CT scan, or MRI. During a physical exam, a doctor may feel a pulsing mass in the abdomen, which is often the first sign of an abdominal aortic aneurysm. An ultrasound can also detect the aneurysm, as it uses sound waves to create images of the aorta and detect any abnormalities. CT scans and MRIs can provide more detailed images of the aneurysm and the surrounding area, allowing for a more thorough diagnosis.
In addition to the physical exam findings, an abdominal aortic aneurysm can also be detected through laboratory tests. A blood test can measure the amount of a protein called C-reactive protein, which is often elevated in people with an aneurysm. An elevated C-reactive protein level can indicate inflammation in the aorta and can be indicative of an aneurysm. An abdominal aortic aneurysm can also be detected through an angiogram, which is an imaging technique that uses X-rays and a contrast dye to create images of the aneurysm and the surrounding area.
In conclusion, the most common exam finding for someone with an abdominal aortic aneurysm is an enlargement of the aorta. However, additional tests such as an ultrasound, CT scan, MRI, blood tests, and angiogram can also be used to detect the aneurysm and provide more information about its size and location.
