颈部淋巴结是甲状腺癌术后最常见的转移部位,大量的临床研究表明,乳头状癌发生颈淋巴结转移只要手术治疗及时正确可以不影响预后[1]。因此相当多的甲状腺癌病人须行颈淋巴结清扫手术。由于颈部具有丰富的淋巴回流,尤其是淋巴导管及乳糜管均在颈部汇入静脉系统,颈淋巴结清扫术后 Cervical lymph nodes are the most common postoperative thyroid cancer metastasis, a large number of clinical studies have shown that cervical lymph node metastasis of papillary carcinoma as long as the timely and correct surgical treatment may not affect the prognosis [1]. Therefore, a considerable number of patients with thyroid cancer cervical lymph node dissection required surgery. As the neck is rich in lymph reflux, especially the lymphatic duct and the chylous line in the neck into the venous system, cervical lymph node dissection
