Intercostal veins

The intercostal veins are a group of veins which drain the area between the ribs ("costae"), called the intercostal space.

There are three main groups:


 * Supreme intercostal vein - 1st intercostal space
 * Superior intercostal vein - 2nd, 3rd, and 4th intercostal spaces
 * Posterior intercostal veins - all 11, on posterior wall
