Thoracic duct commonly terminates in:
Internal jugular vein
External jugular vein
Brachio cephalic vein
None of the above
In rare individuals there is no apparent thoracic duct on the left. Several terminal openings are frequent (10-40%, according to different observers). Patterns vary greatly in different studies, but the commonly repoed sites of termination are internal jugular vein (36-48%), jugulo-subclan junction (35%) and subclan vein (9% and 17%). Termination in the left brachiocephalic vein occurs in 8%.
