The subclavian lymphatic trunk is the continuation of the combined efferent vessels from the apical axillary lymph nodes.

The trunk passes medially:

  • superior to the clavicle
  • anterior to scalenus anterior
  • posterior to the subclavian vein

Near the inner margin of the clavicle it may:

  • on the right side, join the jugular lymph trunk and bronchomediastinal lymph trunk to form the right thoracic duct
  • join the subclavian, internal jugular or brachiocephalic veins directly
  • on the left side, join the thoracic duct
