Abdominal aortic aneurysm


Title




Other Names:
Aneurysm, abdominal aortic
Categories:
Blood Diseases; Congenital and Genetic Diseases; Heart Diseases

Summary Summary


Listen
Abdominal aortic aneurysms (AAAs) are aneurysms that occur in the part of the aorta that passes through the abdomen. They may occur at any age, but are most common in men between 50 and 80 years of age. Many people with an AAA have no symptoms, but some people have a pulsing sensation in the abdomen and/or pain in the back.[1] If the aneurysm ruptures, it may cause deep, severe pain; nausea; vomiting; fast heart rate; clammy skin; and/or shock.[1][2] About 20% of AAAs eventually rupture and are often fatal.[1] The condition has multiple genetic and environmental risk factors, and may sometimes occur as part of an inherited syndrome. When more than one family member is affected, it may be considered "familial abdominal aortic aneurysm."[3] Treatment depends on the size of the aneurysm and may include blood pressure medications, or surgery to repair the aneurysm.[1]

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.

Inheritance Inheritance


Listen
Abdominal aortic aneurysm (AAA) is thought to be a multifactorial condition, meaning that one or more genes likely interact with environmental factors to cause the condition. In some cases, it may occur as part of an inherited syndrome.[3]

Having a family history of AAA increases the risk of developing the condition. A genetic predisposition has been suspected since the first report of three brothers who had a ruptured AAA, and additional families with multiple affected relatives have been reported.[4] In some cases, it may be referred to as " familial abdominal aortic aneurysm."[3] A Swedish survey reported that the relative risk of developing AAA for a first-degree relative of a person with AAA was approximately double that of a person with no family history of AAA. In another study, having a family history increased the risk of having an aneurysm 4.3-fold. The highest risk was among brothers older than age 60, in whom the prevalence was 18%.[4]

While specific variations in DNA (polymorphisms) are known or suspected to increase the risk for AAA, no one gene is known to cause isolated AAA. It can occur with some inherited disorders that are caused by mutations in a single gene, such as Marfan syndrome and Ehlers-Danlos syndrome, vascular type. However, these more typically involve the thoracoabdominal aorta.[4]

Because the inheritance of AAA is complex, it is not possible to predict whether a specific person will develop AAA. People interested in learning more about the genetics of AAA, and how their family history affects risks to specific family members, should speak with a genetics professional.

Find a Specialist Find a Specialist


Listen

If you need medical advice, you can look for doctors or other healthcare professionals who have experience with this disease. You may find these specialists through advocacy organizations, clinical trials, or articles published in medical journals. You may also want to contact a university or tertiary medical center in your area, because these centers tend to see more complex cases and have the latest technology and treatments.

If you can’t find a specialist in your local area, try contacting national or international specialists. They may be able to refer you to someone they know through conferences or research efforts. Some specialists may be willing to consult with you or your local doctors over the phone or by email if you can't travel to them for care.

You can find more tips in our guide, How to Find a Disease Specialist. We also encourage you to explore the rest of this page to find resources that can help you find specialists.

Healthcare Resources

  • To find a medical professional who specializes in genetics, you can ask your doctor for a referral or you can search for one yourself. Online directories are provided by the American College of Medical Genetics and the National Society of Genetic Counselors. If you need additional help, contact a GARD Information Specialist. You can also learn more about genetic consultations from MedlinePlus Genetics.
  • The Marfan Foundation has a Directory of Medical Institutions which is comprised of institutions throughout the United States that treat Marfan syndrome and related conditions.
