20,000 Americans die from a ruptured aorta each year, with 200,000 diagnosed with the threat of rupture of their body's largest blood vessel. Weakening and bulging of the wall of the aorta, causing Abdominal Aortic Aneurysm (AAA) is now believed to be caused by inflammatory pathology mediated by white blood cells called neutrophils. Risk factors for AAA include smoking, hypertension and inherited susceptibility to forming AAA. Symptoms associated with AAAs are back pain and abdominal symptoms and they are diagnosed on examination, x-ray, CT or MRI scan. Treatment for AAA is to control high blood pressure, stop smoking, and surgery is reserved for high-risk aneurysms, which is highly successful.
