Anatomical terminology [edit on Wikidata]

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

They can be divided as follows:

• Anterior intercostal veins
• Posterior intercostal veins
  • Posterior intercost vein that drain into the Supreme intercostal vein - 1st intercostal space
  • Posterior intercost veins that drain into the Superior intercostal vein - 2nd, 3rd, and 4th intercostal spaces. The superior intercostal vein then drains into the Azygous vein.
  • Posterior intercost veins that drain directly into the Azygous vein - in spaces 5–11.
  • Subcostal vein—below bottom (12th) rib and also drains into the Azygous vein.

• Intercostal nerves
