Abstract

To measure the positive predictive value (PPV) of clinical suspicion of abdominal aortic aneurysm (AAA), as confirmed by ultrasonography, we reviewed the records of 343 patients at a university medical center referred to ultrasonography for newly suspected AAA. Positive predictive value was 11.1% for large aneurysms of at least 5.0 cm and 18.7% for aneurysms of at least 3.5 cm, and was higher for men and older patients. For patients under 50 years of age, PPV was only 2.6%. Ultrasonography for clinically suspected AAA has a low positive predictive yield, particularly for men under age 50 and for women.
