Abdominal aortic aneurysm(AAA) occurs when the infrarenal aorta expands to a maximal diameter of 3.0cm or greater. Although AAA may asymptomatic for many years, almost one third eventually rupture if left untreated.

Several randomized trials showed that ultrasonographic screening for AAA could reduce the frequency of acute operations and AAA-related mortality.

However, all of randomized trials were performed in Western countries. There was no randomized trials for AAA screening in Asian countries.

This randomized, controlled trial is to analyze the benefits of screening old population for AAA in Korea.

Estimated Enrollment: 12000
Study Start Date: August 2010
Estimated Study Completion Date: August 2017
Estimated Primary Completion Date: August 2012 (Final data collection date for primary outcome measure)
Detailed Description:

Old population, aged from 60 to 85 years, are randomized into two groups; one group is invited for ultrasonographic screening for AAA, and the other acts as age- and sex-matched controls.

For screening group, The anterioposterior and transverse diameter of the infrarenal aorta is measured at their maximal sizes. The subsequent surveillance of screened patients is done as follows

  • Aortic diameter less than 3.0cm, no further testing
  • AAA 3 to 4cm, ultrasonographic follow-up every year
  • AAA 4 to 5cm, ultrasonographic follow-up every 6 months
  • AAA greater than 5cm, referral to a vascular surgeon

For control group, the information for any causes of death is collected every year.
