This study screened 746 men aged 65-74 for abdominal aortic aneurysms. Undiagnosed abdominal aortic aneurysms were found in 6.3% of participants, with 2% having aneurysms 4.0 cm or larger.

Area of Science:

  • Vascular Surgery
  • Public Health Screening
  • Diagnostic Imaging

Background:

  • Abdominal aortic aneurysm (AAA) is a significant vascular disease.
  • Early detection of AAA can improve patient outcomes.
  • Community-based screening programs are crucial for identifying at-risk populations.

Purpose of the Study:

  • To determine the prevalence of undiagnosed abdominal aortic aneurysms (AAA) in men aged 65-74.
  • To assess the proportion of identified AAAs requiring immediate clinical attention (≥4.0 cm).

Main Methods:

  • Community-based health screening invitation for 1,392 men aged 65-74.
  • Ultrasound imaging of the abdominal aorta to measure anteroposterior diameter.
  • Analysis of screening attendance and AAA prevalence in the attended cohort (n=746).

Main Results:

  • A total of 746 men attended the screening.
  • Prevalence of abdominal aortic aneurysm was 6.3% (n=47).
  • 2% of participants had an abdominal aortic aneurysm measuring 4.0 cm or greater.

Conclusions:

  • Community screening effectively identifies undiagnosed abdominal aortic aneurysms in older men.
  • A significant proportion of screened individuals had large AAAs, highlighting the need for early detection.
  • This study supports the implementation of targeted AAA screening programs for men in this age group.
