An<unk>  is a dilation of the aorta in which the aortic diameter is ≥ 3.0 cm if abdominal or >4 cm if thoracic, usually representing an underlying weakness in the wall of the aorta at that location. While the stretched vessel may occasionally cause discomfort, a greater concern is the risk of rupture which causes severe pain, massive internal hemorrhage which are often fatal. Aneurysms often are a source of blood clots (emboli) stemming from the most common etiology of atherosclerosis.
