Male patient aged 69 years, diabetic, smoker, not hypertensive, or cardiac. Color Doppler shows similar data with PSVst 100 cm/s and PSVdist 17 cm/s (PSVst/PSVdist < 1). a Bilateral severe atherosclerotic changes with diffuse bilateral multiple athermanous plaques with attenuated CIA, EIA, CFA, and SFA at both sides below 50% stenosis then retained accepted opacification of POP A then attenuation of the below-knee arteries. b Lateral view obviously shows the atherosclerotic stenosis of EIA, CFA, and SFA at both sides with attenuated PTA and ATA after a short segment of their origin with nearly non-opacified distal parts especially the ATA. c Multiple athermanous plaques in the Rt CFA with below 50% stenosis. d Attenuated Rt PTA and ATA
