An aortic aneurysm is a bulge or swelling in the wall of the aorta, the largest blood vessel in the body. This condition can occur in different parts of the aorta, including the thoracic aorta in the chest and the abdominal aorta in the abdomen. Aortic aneurysms can develop slowly and may not show symptoms until they become large or rupture, which can be life-threatening. Risk factors for aortic aneurysms include high blood pressure, high cholesterol, smoking, and a family history of the condition. Regular check-ups and imaging tests, such as ultrasounds or CT scans, can help detect aneurysms early. Treatment options may include monitoring smaller aneurysms or surgical intervention for larger ones.
