Summary
Targeted screening for abdominal aortic aneurysms (AAA) in high-risk men and women is cost-effective. Early detection and repair, based on size and expansion rate, can significantly reduce AAA mortality.
Area of Science:
- Vascular Surgery
- Public Health Screening
- Cardiovascular Medicine
Context:
- Infrarenal abdominal aortic aneurysm (AAA) screening programs show limited overall cost-effectiveness.
- Specific subpopulations, including smoking men aged 60-75 and those with family history or comorbidities, benefit from cost-effective screening.
- AAA mortality rates are increasing, necessitating effective interventions.
Purpose:
- To evaluate the cost-effectiveness of targeted AAA screening strategies.
- To define optimal criteria for AAA repair and surveillance based on patient demographics and aneurysm characteristics.
- To reduce AAA-related mortality through improved screening and management protocols.
Summary:
- Screening is cost-effective for smoking men (60-75 years) and individuals with a family history of vascular disease or cardiovascular comorbidities.
- Elective AAA repair is recommended for men with >5.5 cm diameter and women with 4.5-5 cm diameter.
- Annual surveillance should monitor aneurysm expansion rate, recommending repair for >0.5 cm annual growth.
Impact:
- Implementation of targeted screening can halve AAA mortality.
- Personalized management strategies improve patient outcomes and resource allocation.
- Early detection and timely intervention are crucial for preventing AAA rupture and associated deaths.
