Utility of duplex ultrasound in detecting and grading de novo femoropopliteal lesions
Arterial Occlusive Diseases
Ultrasonography, Doppler, Duplex
DUS shows a strong agreement with angiography and has good accuracy in detecting femoropopliteal lesions. We propose DUS criteria of PSV 200 cm/s and Vr 2.0 to differentiate between <70% and ≥70% de novo stenosis in the femoropopliteal arterial segment.
