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
[edit]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.[1][2]
Left superior intercostal vein
[edit]The left superior intercostal vein drains the 2nd and 3rd posterior intercostal veins on the left side of the body. It usually drains into the left brachiocephalic vein.[1][2] It may also communicate with the accessory hemiazygos vein.[2]
As it passes posteriorly above the aortic arch, it crosses deep to the phrenic nerve and the pericardiacophrenic vessels and then superficial to the vagus nerve.
