What was done
The authors conducted a review of the literature evaluating the basic anatomy, anatomical variations, and clinical relevance of the right lymphatic duct and right-sided terminations of the thoracic duct.
What was found
Right-sided terminations of the thoracic duct into the venous system are present in approximately 1% to 6% of humans. Reported rates of chyle leak from right-sided neck dissections ranged widely across studies, accounting for 0%, 14%, 24%, 33%, or 60% of total neck surgery chyle leaks. Other documented right-sided conditions include chyle leaks after right anterior cervical spine surgery, right lymphatic duct cysts, and right lymphatic duct dilatation presenting as recurrent cervical swelling.
Why it matters
Although cervical chyle leaks are classically associated with left-sided operations, recognition of right lymphatic duct anatomy and right-sided thoracic duct variants is necessary to prevent and manage iatrogenic injury during right-sided neck procedures.
Limits
The abstract describes a narrative review with no systematic search protocol, formal quality appraisal, or stated total sample size. The wide range of reported leak rates (0% to 60%) reflects substantial heterogeneity and potential reporting bias in the primary literature.
