Sensitivity and Specificity of Ankle-Brachial Index for Detecting Angiographic Stenosis of Peripheral Arteries

Abstract

The ABI value shows a decreasing tendency with increasing severity of stenosis in patients with PAD. ABI measurement is an accurate and reliable noninvasive alternative to conventional DSA in the assessment of lower extremity arteries and the cut-off of 0.95 is the threshold ABI value for detecting PAD in Chinese patients.
