Can Lower Limb Ultrasonography Replace Arteriography?

Abstract

Although duplex ultrasonography offers a number of theoretical and practical advantages over arteriography for the assessment of lower limb arterial disease, it has not yet been widely accepted into clinical practice. This article reviews the current status of lower limb arterial duplex and concludes that arteriography should no longer be regarded as the diagnostic ‘gold-standard’ and that duplex ultrasonography should now be the first line investigation in patients with lower limb arterial disease.
