MedicalResearch.com: What is the background for this study?
Response: An abdominal aortic aneurysm (AAA) is a bulge in the wall of the main artery that carries blood from the heart to the lower part of the body. While AAA often has no signs or symptoms, the aneurysms can grow silently and burst without warning, which can be deadly.
MedicalResearch.com: What are the main findings?
Response: The Task Force found that men ages 65 to 75 who smoke or used to smoke should receive one-time screening for AAA. Women who have never smoked and have no family history of the condition should not be screened.
MedicalResearch.com: What should readers take away from your report?
Response: The key takeaway from this recommendation is that men aged 65 to 75 who smoke or used to smoke are likely to benefit from one-time screening for abdominal aortic aneurysm. Men aged 65 to 75 who have never smoked may want to consider screening. Women who have never smoked and have no family history of AAA should not be screened.
It’s important to note that whether someone may benefit from screening for AAA depends on several risk factors including their sex, age, smoking status, and family history. It’s critical that clinicians discuss these risk factors with their patients to help them make an informed decision about how best to approach AAA screening, taking into account their individual risk level, as well as their values and personal preferences.
MedicalResearch.com: What recommendations do you have for future research as a result of this work?
Response: As part of this recommendation, the Task Force is calling for more research on the benefits and harms of screening for abdominal aortic aneurysm in women who have ever smoked or have a family history of the condition, since we were not yet able to make a recommendation for this group. Further research is also needed to help us better understand what size AAAs in women should be treated and to determine whether someone whose first screening result shows they do not have abdominal aortic aneurysm should ever be screened again and how often.
MedicalResearch.com: Is there anything else you would like to add?
Response: While screening for abdominal aortic aneurysm can be lifesaving, just like any procedure, it can also cause harms. For example, screening can find aneurysms that would have never ruptured, leading to unnecessary surgeries that may result in serious health problems and even death. Because of the potentially serious harms of treatment, it’s important to only screen people for whom the benefits are likely to outweigh the potential harms.
