Ultrasonography images (color flow Doppler imaging). A: A short-axis view of the left side of the neck. On the first ultrasound examination, a hyperechoic region of the thrombus in the left jugular vein thrombus coexisted with a hypoechoic region, which occluded the left jugular vein (arrow). B: The left subclavian approach. On the first ultrasound, a thrombus was present in the left subclavian vein (triangle) and another thrombus was present in the left brachiocephalic vein (arrow). C: The left subclavian approach. After 1 month of edoxaban treatment, the thrombi in the left subclavian vein (triangle) and left brachiocephalic vein (arrow) were smaller, and blood flow through these veins was increased.

Ultrasonography and enhanced computed tomography (CT) revealed thrombosis of the left internal jugular vein, left subclavian vein, and left brachiocephalic vein (Fig. 1A and B, 2). One month later, ultrasonography showed smaller thrombi and increased blood flow through the left subclavian and brachiocephalic veins (Fig. 1C).
