The supreme intercostal vein (highest intercostal vein) is a paired vein that drains the first intercostal space on its corresponding side.
It can drain into either the brachiocephalic vein, the superior intercostal vein, or the vertebral vein of its corresponding side.
This vein does not have valves, this is an important point when it comes to spread of cancerous secondaries.
