【摘要】 目的总结甲状腺手术术前判定和术中识别非返性喉返神经经验。方法回顾性分析中国医科大学附属第一医院血管甲状腺外科2008年8月至2010年2月甲状腺病人存在非返性喉返神经4例病人的临床资料,探讨非返性喉返神经的术前判定和术中识别及保护技巧。结果4例均为右侧ⅡA型非返性喉返神经,术前颈部增强CT提供诊断依据,手术均无损伤。结论术前颈部增强CT发现食管后方异常右锁骨下动脉,高度提示右侧非返性喉返神经存在,术中仔细操作,有助于避免损伤。更多还原

【Abstract】 Objective To evaluate preoperative judgment and intraoperative identification of nonrecurrent laryngeal nerve(NRLN) during thyroidectomy.Methods The clinical data of 4 cases of thyroid surgery associated with a right NRLN from August 2008 to February 2010 in the Department of Vascular and thyroid,the First Hospital of China Medical University were analyzed retrospectively.Results The preoperative CT scan showed a retroesophageal aberrant right subclavian artery in all 4 cases.They had identification of TypeⅡA NRLN on the right side.Postoperatively,the patient had normal vocal cord function on laryngoscopy.Conclusions It is possible to predict preoperatively a right NRLN by identifying an aberrant right subclavian artery on the CT film of the neck,which likely enabled the prevention of vocal cord paralysis.更多还原
