Internal jugular vein thrombus. Grayscale ultrasound images of the same patient in Fig. 7 with (a) and without compression (b) demonstrating heterogeneous echogenic material within the jugular vein which was noncompressible (arrow), findings consistent with thrombus. Note the catheter within the vessel. c Color Doppler ultrasound image demonstrate lack of blood flow (arrows) in the internal jugular vein confirming the presence of thrombus
