[3] The brachiocephalic veins are the major veins returning blood to the superior vena ...
The left superior vena cava is not shown in this image. In anatomy , a persistent left superior vena cava is the most common variation of the thoracic venous system . [ 1 ] [ 2 ] It is present in between 0.3% and 0.5% of the population, [ 3 ] [ 4 ] [ 5 ] and is an embryologic remnant that results from a failure to involute .
The superior vena cava is formed by the left and right brachiocephalic veins, which receive blood from the upper limbs, head and neck, behind the lower border of the first right costal cartilage.
