Abdominal Aortic Aneurysm (AAA) is a condition in which the walls of the abdominal aorta are weakened and bulge out. It is a serious condition and can be life-threatening if left untreated. It is important to know who is at risk for AAA so that early detection and treatment can be sought.
What is an Abdominal Aortic Aneurysm?
An abdominal aortic aneurysm (AAA) is a weakened area in the wall of the abdominal aorta, the largest artery in the body. The aneurysm can cause the walls of the artery to bulge out, creating a balloon-like sac. If left untreated, an abdominal aortic aneurysm can rupture, causing potentially life-threatening internal bleeding.
Who is at Risk for Abdominal Aortic Aneurysm?
Men aged 65 years and older are at the highest risk for developing an abdominal aortic aneurysm. Other risk factors include:
Smoking: Smoking is the most important risk factor for developing an abdominal aortic aneurysm.
Family History: Those with a family history of abdominal aortic aneurysms are at a higher risk of developing an aneurysm.
High Blood Pressure: High blood pressure can increase the risk of an abdominal aortic aneurysm.
Atherosclerosis: Atherosclerosis, or hardening of the arteries, can weaken the walls of the abdominal aorta and increase the risk of an aneurysm.
Other Conditions: Certain other conditions, such as Marfan syndrome, Ehlers-Danlos syndrome, and polycystic kidney disease, can increase the risk of developing an abdominal aortic aneurysm.
Screening for Abdominal Aortic Aneurysm
Men aged 65 and older who have risk factors for abdominal aortic aneurysm should be screened. Screening is done with an ultrasound of the abdomen. This procedure is non-invasive and can detect an aneurysm before it ruptures. If an aneurysm is found, it can be monitored and treated if necessary.
Conclusion
Abdominal aortic aneurysms are serious and potentially life-threatening conditions. Men aged 65 years and older are at the highest risk for developing an abdominal aortic aneurysm. Other risk factors include smoking, family history, high blood pressure, atherosclerosis, and certain other conditions. Men aged 65 and older should be screened for abdominal aortic aneurysm with an ultrasound of the abdomen. Early detection and treatment can prevent life-threatening complications.
