The superior vena cava (SVC) is a large valveless venous channel formed by the union of the brachiocephalic veins. It receives blood from the upper half of the body and returns it to the right atrium1.
It begins behind the lower border of the first right costal cartilage and descends vertically behind the second and third intercostal spaces to end in the right atrium at the level of the third costal cartilage. Its lower half is covered by the fibrous pericardium, which it pierces at the level of the second costal cartilage1.
