Subclavian trunk

Radiopaedia • CC-by-nc-sa 3.0 • de

The subclavian trunks are small short paired lymphatic trunks, each one draining its respective upper limb, and formed from efferent lymphatics draining from the apical (subclavicular) subgroup of the axillary nodes.

In turn the subclavian trunks pass through the cervicoaxillary canal and drain into the:

  • right lymphatic duct/thoracic duct, or
  • jugulosubclavian venous junction (venous angle), or
  • jugular lymphatic trunk.
