Abstract: Objective To analyze the clinical characteristics and treatment methods of 50 patients with hemorrhage after thyroid surgery，and explore the prevention and treatment of postoperative thyroid bleeding.
Methods The clinical data of 50 patients with hemorrhage after thyroid surgery from January 2015 to November 2019 were retrospectively analyzed.These patients were divided into surgical treatment group（29 cases） and non-surgical treatment group（21 cases） according to the treatment for the postoperative bleeding.The clinical characteristics of the two groups were compared.
Results The results of univariate analysis showed that gender，cause of bleeding，time from the end of thyroid surgery to the discovery of bleeding，and neck symptoms during bleeding were statistically significant in the two groups of cases（P<0.05）.Male（OR value1.38）and Neck swelling（OR value 2.68）was an independent influencing factor for surgical hemostasis.The surgical treatment group found that the most common bleeding site was the anterior jugular vein and its communicating branch with the latissimus dorsi flap.
Conclusion Male and neck swelling is an independent influencing factor for surgical hemostasis.Before closing the incision in thyroid surgery，special attention should be paid to the examination of the anterior jugular vein and the branch of communication with the latissimus dorsi flap.
