Overview
An abdominal aortic aneurysm is a localized dilatation of the abdominal aorta, that exceeds the normal diameter of the abdominal aorta by more than 50%. The normal diameter of an aorta depends on the patient's age, sex, height, weight, race, body surface area, and baseline blood pressure. On average, the normal diameter of the infrarenal aorta is 2 cm, and therefore a true AAA measures 3.0 cm or more. Aortic ectasia is a mild generalized dilatation (<50% of the normal diameter of ≤ 2.9 cm) that is due to age-related degenerative changes in the vessel walls.
Causes
Life Threatening Causes
Abdominal aortic aneurysm is a life-threatening condition and must be treated as such irrespective of the underlying cause.
Common Causes
FIRE: Focused Initial Rapid Evaluation
A Focused Initial Rapid Evaluation (FIRE) should be performed to identify patients in need of immediate intervention.
Abbreviations:
Complete Diagnostic Approach
A complete diagnostic approach should be carried out after a focused initial rapid evaluation is conducted and following initiation of any urgent intervention.
Treatment
Shown below is an algorithm summarizing the treatment of Abdominal aortic aneurysm according the the [...] guidelines.
