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.
