Summary
Screening for abdominal aortic aneurysms (AAA) is vital for early detection of this life-threatening vascular disease. Ultrasound is the primary recommended imaging method for asymptomatic adults.
Area of Science:
- Vascular Surgery
- Diagnostic Imaging
- Preventive Cardiology
Background:
- Abdominal aortic aneurysm (AAA) affects 4-8% of screened individuals.
- AAA rupture has a high mortality rate (75-90%) and contributes to sudden deaths.
- Asymptomatic screening is crucial for preventive healthcare worldwide.
Purpose of the Study:
- To outline the importance and methods for screening abdominal aortic aneurysms.
- To provide evidence-based guidelines for AAA screening.
Main Methods:
- Review of the American College of Radiology Appropriateness Criteria.
- Systematic analysis of peer-reviewed medical literature.
- Adaptation of evidence evaluation principles like GRADE.
- Utilizing the RAND/UCLA Appropriateness Method for imaging procedures.
Main Results:
- Ultrasound of the abdominal aorta is the primary recommended screening modality.
- Duplex ultrasound and non-contrast CT abdomen/pelvis are alternative screening options.
- Guidelines are based on evidence evaluation and expert consensus when literature is lacking.
Conclusions:
- Early screening for abdominal aortic aneurysms is essential for reducing mortality.
- Ultrasound is the preferred imaging technique for AAA screening in asymptomatic adults.
- Evidence-based guidelines ensure appropriate and effective screening practices.
