It's not 100% accurate but it IS a good idea for folks who are asymptomatic but have family members who've had AAA to be screened themselves, especially first degree relatives (parents-childen-siblings) because there is some incidence of it being a familial trait. But if there's no family history and no other symptoms (a pulsation in the belly area, for example) it's not generally recommended as a screening test. And you can get false negatives, as well, especially if the aneurysm is small and you're not.
The Canadian Task Force on Periodic Examination has looked at this. Their conclusion is "physical examination may be considered prudent for men over 60, however, and that ultrasound screening could be considered in selected high-risk men over 60: smokers with other risk factors for AAA (hypertension, claudication, family history, or other vascular disease.)
