Answer

Doppler ultrasonographic studies are useful as primary noninvasive studies to determine flow status. Upper extremities are evaluated over the axillary, brachial, ulnar, and radial arteries. Lower extremities are evaluated over the femoral, popliteal, dorsalis pedis, and posterior tibial arteries. Note the presence of Doppler signal and the quality of the signal (ie, monophasic, biphasic, triphasic). The presence of distal flow does not exclude emboli or thrombi because collateral circulation may provide these findings.
