Thoracic duct
----------------------
The thoracic duct is the main lymphatic channel for the return of chyle to the venous system. It drains lymph from both lower limbs, abdomen (except the convex area of the liver), left hemithorax, left upper limb and left face and neck.
Gross anatomy
------------------------
The thoracic duct is the superior continuation of the cisterna chyli at the level of the L1 vertebral body (range T10-L3).
The thoracic duct enters the thoracic cavity through the aortic hiatus and ascends to the right of the midline in the posterior mediastinum between the aorta and azygos vein, posterior to the oesophagus.
It crosses to the left of midline at the thoracic plane (range T4-T6 vertebral body) and continues superiorly through the thoracic inlet, posterior to the left subclavian artery and continues in the neck anterior to the anterior scalene muscle and phrenic nerve. At the root of the neck, it arches forwards and to the left, behind the carotid sheath and its contents 7. Crossing over the dome of the pleura and left subclavian artery to drain into the angle of the left subclavian and internal jugular veins as a single trunk 1-4.
In its terminal (distal) portion the thoracic duct may be more often flared or dilated rather than continue at a consistent diameter 1.
Relations
---------------
anterior: oesophagus, left atrium, carina
posterior: vertebral column, terminal hemiazygos and accessory hemiazygos veins, right posterior intercostal arteries
left lateral: descending aorta, left lung and pleura
right lateral: azygos vein, right lung and pleura
Tributaries
-----------------
In the Thorax:
the lower 6 or 7 intercostal spaces are drained by the posterior intercostal lymph nodes which then drain into the right and left descending thoracic lymph trunks which open near the origin of the thoracic duct on either side
upper left intercostal lymph trunk is responsible for draining the left upper 5 intercostal spaces which then drain into the more distal, left side of the thoracic duct
posterior mediastinal lymph node efferents
the thoracic duct also receives right and left trunks that drains the upper lumbar lymph glands, near its origin
Near its termination:
left jugular lymph trunk (draining left side of head and neck)
left subclavian lymph trunk (draining left axilla and upper limb)
left bronchomediastinal trunk (draining left lung and heart)
