Vena intercostalis superior dextra

Origin

The right superior intercostal vein is formed by the union of the second and third, and sometimes the fourth, posterior intercostal veins on the right-hand side.

Course

From its origin, the right superior intercostal vein travels inferiorly to reach the azygos vein. It is one of the last tributaries of the azygos vein before it returns blood to the superior vena cava.

Tributaries

There are no named tributaries.

Structures Drained

Since the right superior intercostal vein receives the second and third posterior intercostal veins, it indirectly drains the muscles of the intercostal space, muscle of the back, vertebral column, and overlying skin.
