The aorta is the main arterial blood vessel that carries oxygenated blood to the organs. An aortic aneurysm is a localized dilatation of the aortic wall and most often affects its abdominal section. Symptoms that may appear are throbbing, abdominal or back pain, but the disease is usually asymptomatic. The rupture of aneurysm poses the greatest risk, which often has a fatal outcome. The diagnosis is determined by ultrasound or MSCT angiography, and it is treated surgically or endovascularly.
