Figure 19.
Occlusive DVT of the femoral vein in an 88-year-old man who had been hospitalized with COVID-19. Gray-scale (left) and color Doppler (right) US images obtained in the transverse plane show dilated femoral veins (white arrows), with internal heterogeneous echogenic material and absence of flow on the color Doppler US image, findings compatible with occlusion. The veins were noncompressible (not shown). Note that the femoral artery is filled with color, indicative of patency (black arrows).
