Arterial duplex for diagnosis of peripheral arterial emboli Jeffrey D. Crawford, MD, Kenneth H. Perrone, BS, Enjae Jung, MD, Erica L. Mitchell, MD, Gregory J. Landry, MD, Gregory L.

Fig 1 Lower extremity (LE) arterial velocity by duplex and rate of fasciotomy. AT, Anterior tibial artery; CFA, common femoral artery; Profunda, profunda femoris artery; PSV, peak systolic velocity; PT, posterior tibial artery; SFA, superficial femoral artery.

Fig 2 Overall survival by duplex ultrasound (DUS) and contrast angiography/computed tomography angiography (CA/CTA) as the diagnostic imaging modality. The standard error does not exceed 0.10 (range, 0.5-0.9).

Fig 3 Contrast angiography (CA) and duplex ultrasound (DUS) imaging for acute limb ischemia (ALI). Acute occlusion of the distal right superficial femoral artery is demonstrated by (A) CA and (B) DUS imaging. B, A heterogenous, intraluminal embolus can be seen with B mode and an absence of arterial flow by pulsed Doppler. C, Distal to the embolus there is a monophasic waveform and flow in the popliteal artery with peak systolic velocity (PSV) of 15 cm/s.
