Abstract WP130: Validation of Multi-parametric Ultrasonography Criteria with Catheter Angiography in Internal Carotid Artery Disease: A Prospective Multicenter Study

Introduction: Novel multi-parametric criteria for duplex ultrasonography (DUS) grading of extracranial internal carotid artery (ICA) steno-occlusive disease have been recently introduced by the German ultrasound expert panel (DEGUM). We sought to determine diagnostic accuracy of the DEGUM criteria against the gold standard catheter angiography. Methods: We prospectively enrolled consecutive patients who routinely underwent diagnostic or...
