Innominate vein
Extracted from the Wikipedia article Brachiocephalic vein.
The left and right brachiocephalic veins (previously called innominate veins) are major veins in the upper chest, formed by the union of the ipsilateralinternal jugular vein and subclavian vein (the so-called venous angle) behind the sternoclavicular joint. The left brachiocephalic vein is more than twice the length of the right brachiocephalic vein.
