Anatomical terminology

The left and right brachiocephalic veins (or innominate veins) are major veins in the upper chest, formed by the union of each corresponding internal jugular vein and subclavian vein.[1] This is at the level of the sternoclavicular joint.[2] The left brachiocephalic vein is nearly always longer than the right.[3]

These veins merge to form the superior vena cava, a great vessel, posterior to the junction of the first costal cartilage with the manubrium of the sternum.[4][5]

The brachiocephalic veins are the major veins returning blood to the superior vena cava.[3]

Tributaries

Veins of the thoracic and abdominal regions

The brachiocephalic vein is formed by the confluence of the subclavian and internal jugular veins.[1] In addition it receives drainage from:

Embryological origin

The left brachiocephalic vein forms from the anastomosis formed between the left and right anterior cardinal veins when the caudal portion of the left anterior cardinal vein degenerates.
