Reliability and Accuracy of Peri-Interventional Stenosis Grading in Peripheral Artery Disease Using Color-Coded Quantitative Fluoroscopy: A Phantom Study Comparing a Clinical and Scientific Postprocessing Software

<div>A 57-year-old patient with PAD (Rutherford 3 PAD classification) and an occlusion of the superficial femoral artery are shown (a). After balloon angioplasty a residual high-grade stenosis is visible (b) which was treated successfully by stent placement (c). Time-density curves of the treated patient case before (d) and after (e) stent angioplasty highlight the flow restriction through a high-grade stenosis.</div>
