Anterior Vena Cava

ANTERIOR VENA CAVA

  • The anterior vena cava is formed by the union of the external jugular vein and brachial vein on either side.
  • This is a large venous trunk receiving venous blood from the head, neck, fore limbs and a large part of the thoracic wall.
  • It is about 10 to 14 cm long and it passes in the anterior mediastinum below the trachea and right vagus, deviating to the right of the brachiocephalic trunk and its branches.
  • It opens into the right atrium where it is covered by pericardium.
  • It receives in its course the internal thoracic vein and the thoracic duct at the thoracic inlet on its superior face.
