Abdominal aortic aneurysm
Abdominal aortic aneurysm (pronunciation: /æbˈdɒmɪnəl ˈɔːr.tɪk æn.jʊəˈrɪz.əm/) is a localized enlargement of the abdominal aorta such that the diameter is greater than 3 cm or more than 50% larger than normal diameter. They usually cause no symptoms except when ruptured. Occasionally, abdominal, back, or leg pain may occur. Large aneurysms can sometimes be felt by pushing on the abdomen. Rupture may result in pain in the abdomen or back, low blood pressure, or loss of consciousness, and often results in death.
Etymology
The term "Abdominal aortic aneurysm" is derived from the Greek word "aneurysma", meaning "dilation". "Abdominal" refers to the part of the body where this condition occurs, and "aortic" refers to the aorta, the main blood vessel that supplies blood to the body.
