The superior intercostal veins are two veins that drain the 2nd, 3rd, and 4th intercostal spaces, one vein for each side of the body.

Right superior intercostal vein

The right superior intercostal vein drains the 2nd, 3rd, and 4th posterior intercostal veins on the right side of the body. It flows into the azygos vein.

Left superior intercostal vein

The left superior intercostal vein drains the 2nd and 3rd posterior intercostal veins on the left side of the body. It drains into the left brachiocephalic vein. It may also communicate with the accessory hemiazygos vein.
