subclavian vein

 

brachiocephalic vein or innominate vein

 

axillary vein

- axillary artery (red arrow)

vascular occlusion

- subclavian vein oclcusion

subclavian vein occlusion

- thrombus observed in the left subclavian vein (arrow), raising suspicion of occlusion, the distal subclavian and axillary veins (arrowheads) are enhanced because of backflow of venous blood from a possible arteriovenous fistula
