Vessel
Right lymphatic duct
A variable final lymphatic channel at the right neck base
High-yield
The right upper body is its usual drainage territory. Connections and terminal openings vary, so the standard right-versus-left diagram is a guide rather than an absolute boundary.
Overview
When present as a common duct, this short vessel gathers lymphatic trunks serving the right upper limb, right head and neck, and part of the thorax. The trunks may instead enter adjacent veins separately.
Reference facts
- Origin
- Variable union of right jugular, subclavian and bronchomediastinal trunks
- Course
- A short terminal course at the root of the right neck near the jugular–subclavian venous junction
- Branches
- These are incoming tributaries, not arterial-style branches; they may join in different combinations or open independently
- Drains to
- Right internal jugular, subclavian or brachiocephalic venous region, often near the venous angle
Clinical correlation
Injury to a terminal lymphatic channel during neck procedures can cause a lymph leak. Variant connections matter on either side of the neck.
Frequently asked questions
Where does the right lymphatic duct originate?
The right lymphatic duct arises from the variable union of right jugular, subclavian and bronchomediastinal trunks.
Where does the right lymphatic duct drain to?
The right lymphatic duct drains to the right internal jugular, subclavian or brachiocephalic venous region, often near the venous angle.
What are the tributaries of the right lymphatic duct?
These are incoming tributaries, not arterial-style branches; they may join in different combinations or open independently.
What is the course of the right lymphatic duct?
A short terminal course at the root of the right neck near the jugular–subclavian venous junction.
