Screening for abdominal aortic aneurysm (AAA) Research studies suggest that a routine ultrasound scan is worthwhile for all men aged 65. This is because most people with an AAA do not have symptoms. Following a routine scan, surgery can be offered to men found to have an aneurysm over 5.5 cm wide.
Abdominal Aortic Aneurysm. When the wall of a blood vessel weakens, a balloon-like dilation called an aneurysm sometimes develops. This happens most often in the abdominal aorta, an essential blood vessel that supplies blood to your legs. Every year, 200,000 people in the U.S. are diagnosed with an abdominal aortic aneurysm (AAA). A ruptured AAA is the 15th leading cause of death in the country, and the 10th leading cause of death in men older than 55. Aneurysms run in families.
