Objective: In combination with the literature analysis of the anatomical variation characteristics of the cervical thoracic catheter and the treatment strategy of celiac leakage, it provides a certain reference role for the prevention and treatment of clinical right cervical lacetic leakage. Methods: Report the medical record data of a young male patient who underwent thyroid cancer neck lymph node clearance after lymph node clearance of the right neck, and retrieve the relevant literature of lymphosis after cervical lymph node clearance through the Chinese and English database, analyse the reason for the rare right cervical lymph node clearance, and explore the best treatment method. Conclusion: It is rare to have leary leakage on the right side after cervical surgery. If the amount of fluid leakage is relatively large, it is often due to the mutation of the thoracic catheter compared with the normal anatomical position, and the leakage volume of >4000ml/d after conservative treatment should be surgically treated as soon as possible. Thoracoscopic ligation is a good choice.
