Question

Cutoff for surgery in an abdominal aortic aneurysm in asymptomatic patientsa)

• A. 5.5cm
• B. 6.5cm
• C. 7.5cm
• D. 8.5cm

Answer 1

The Correct Option is A

Abdominal aortic aneurysms (AAAs) are enlarged areas in the lower part of the body's main artery (aorta) that pass through the abdomen. These are often asymptomatic until they become large or rupture. The management of asymptomatic AAAs is critical to prevent rupture, which can be life-threatening. Surgical intervention is typically considered based on the size of the aneurysm:

• Cutoff for Surgery: 5.5 cm—Research and clinical guidelines suggest that asymptomatic abdominal aortic aneurysms should be repaired surgically when they reach a diameter of approximately 5.5 cm or larger. This threshold has been found to be a balance between the risks of surgical intervention and the risk of rupture, which significantly increases as the aneurysm enlarges.

In summary, the cutoff for surgery in an asymptomatic patient with an abdominal aortic aneurysm is 5.5 cm.
