Abstract



Background


Digital subtraction angiography (DSA) is the gold standard for diagnosing lower extremity (LE) arterial lesions. However, duplex ultrasound (DUS) is a widely used, safe, and noninvasive method of detecting LE lesions. The purpose of this study was to establish DUS criteria for detecting and grading de novo stenotic lesions in the femoropopliteal arterial segment.



Methods


A prospective database was established including all patients who underwent LE endovascular interventions between 2004 and 2009. Patients with de novo stenotic lesions in the femoropopliteal segment were selected. DUS and DSA data pairs ≤30 days apart were analyzed. Peak systolic velocity (PSV; cm/s), velocity ratio (Vr), and DSA stenosis were noted. Linear regression and receiver operator characteristic (ROC) curves were used.
