Summary

Opportunistic screening for abdominal aortic aneurysm (AAA) in men aged 65-74 is effective. Measuring aortic diameter during routine ultrasounds identifies AAA prevalence comparable to dedicated programs, facilitating timely management.

Area of Science:

  • Vascular Surgery
  • Radiology
  • Public Health

Background:

  • Abdominal aortic aneurysm (AAA) screening is debated.
  • Early detection and management of AAA are crucial for preventing rupture.

Purpose of the Study:

  • To assess the prevalence of AAA in a specific demographic.
  • To evaluate the feasibility and impact of opportunistic AAA screening.

Main Methods:

  • Investigated AAA prevalence in 317 male patients aged 65-74 undergoing abdominal ultrasonography.
  • Assessed clinician knowledge and management practices regarding AAA detection.

Main Results:

  • 15% of patients had AAA (>=30mm), 5% had larger aneurysms (>=40mm).
  • Delayed management initiation for detected AAAs.

  • Significant variation in clinician knowledge and intended management of AAA.

    • Conclusions:

    • Opportunistic AAA screening during abdominal ultrasonography is cost-effective and identifies a prevalence similar to population screening.
    • Routine aortic diameter measurement can screen 12-15% of at-risk men within five years without extra resources.
