Abdominal Aorta Ultrasound (AAA Screening)

The aorta is the body’s largest artery. An abdominal aortic aneurysm (AAA) is a bulge in its wall that often causes no symptoms until it becomes dangerous. Ultrasound safely measures the aorta’s diameter to detect and track aneurysms.

The U.S. Preventive Services Task Force recommends a one-time AAA ultrasound screening for men aged 65–75 who have ever smoked.
