<p><strong>What is Abdominal Aortic Aneurysm?</strong><br />
Abdominal aortic aneurysm (AAA) is permanent focal dilatation of aorta artery to more than one and half times its diameter. This causes a bulge in the abdominal area. Small and slow growing abdominal aortic aneurysms do not rip open. However, large and fast-growing aortas may rupture suddenly leading to internal bleeding. This could be fatal. Nonetheless, if you adopt regular treatment for abdominal aortic aneurysm, doctors monitor your condition and plan surgery accordingly. Often, you do not display any symptoms of abdominal aortic aneurysm.</p>
<p>Aorta is the main blood vessel supplying blood to all body parts. Its elastic nature allows it to expand with blood under high pressure. However, thin aorta walls cannot support extended elasticity and rupture if aorta becomes too huge. Abdominal aortic aneurysm is very common in men in the age group of 65 to 75 years.</p>
<p><strong>Diagnosis of Abdominal Aortic Aneurysm</strong></p>
<p>Abdominal aortic aneurysm is normally diagnosed by physical examination and ultrasound. Plain abdominal radiographs show aorta outline clearly. Ultrasound detects present size of aorta. Presence of free peritoneal fluid also indicates aneurysm. However, obesity and bowel gas limit these detections. CT scan detects aneurysm correctly. Doctors depend on CT scan to plan course of action. Medical software computes data available through standard clinical CT scan and provides abdominal aortic aneurysm rupture risk diagnosis according to specific individual.</p>
<p>Angiography and MRI are less commonly used in diagnosing abdominal aortic aneurysm.</p>
