An aortic aneurysm is a bulge or dilation in the wall of the aorta, the largest blood vessel in the body. This condition can occur in any part of the aorta, but it is most common in the abdominal area. Aortic aneurysms can develop slowly over time and may not cause symptoms until they become large or rupture, leading to serious complications. Risk factors for an aortic aneurysm include high blood pressure, high cholesterol, smoking, and a family history of the condition. Regular check-ups and imaging tests, such as ultrasound or CT scans, can help detect an aneurysm early, allowing for timely treatment to prevent rupture.
