Duplex Ultrasound Versus Conventional Angiography in Evaluating Lower Limb Threatening Ischemia
Sponsor: Sohag University
Summary
This study aims to evaluate the accuracy of Duplex Ultrasound (DUS) in assessing infra inguinal arterial lesions in patients with chronic threatening limb ischemia compared with digital subtraction angiography (DSA) as the reference standard. By comparing sensitivity, specificity, and predictive values across arterial segments, the study seeks to determine the clinical utility of DUS as a non-invasive alternative for pre-intervention vascular mapping in chronic limb-threatening ischemia.
