Figure 23c.

Extensive bilateral upper extremity DVT in a critically ill 77-year-old man with COVID-19 who developed bilateral upper extremity swelling, with markedly elevated d-dimer levels (31 447 ng/mL). (a, b) Sagittal color (a) and power (b) Doppler US images show absent flow in the distended vein, with echogenic material in the left subclavian vein (arrow in a) and the right axillary vein (arrows in b), compatible with bilateral occlusive thrombi. Additional occlusive and nonocclusive thrombi were also seen (not shown). (c) Gray-scale US images without (left) and with (right) compression show a thrombus (arrows) in the right cephalic vein, which demonstrates no vascular compression (arrows).
