A 71-year-old woman was admitted to the Emergency Department with severe dyspnea followed by unconsciousness. She had a history of hyperthyroidism and her anterior neck was markedly swollen. After ventilation was started, she soon became conscious with the improvement of oxygenation. Computed tomography findings indicated giant goiter surrounding the trachea. Later, we carried out a thyroidectomy for the giant goiter (800 g), and tracheostomy. Bronchoscopy carried out at the end of surgery showed a deformed tracheal wall on breathing. During inspiration, the collapsed wall of the trachea occluded the airway, although the tracheal wall recovered to normal during expiration. We diagnosed this case as acquired tracheomalacia and a tracheal stent graft made of silicon was inserted immediately after bronchoscopy.
After stent graft insertion, the patient was transferred to another hospital.
Emergency physicians should be aware of the causes of tracheomalacia in order to safely carry out treatment, particularly in the case of patients with giant goiter.
一名71岁女性因严重呼吸困难继而昏迷被收入急诊科。她有甲状腺功能亢进病史,其颈部前方明显肿胀。开始通气后,随着氧合改善她很快苏醒。计算机断层扫描结果显示巨大甲状腺肿包绕气管。后来,我们对巨大甲状腺肿(800克)实施了甲状腺切除术及气管造口术。手术结束时进行的支气管镜检查显示呼吸时气管壁变形。吸气时,气管塌陷的壁阻塞气道,尽管呼气时气管壁恢复正常。我们将此病例诊断为获得性气管软化,并在支气管镜检查后立即插入了由硅制成的气管支架移植物。
插入支架移植物后,患者被转至另一家医院。
急诊医生应了解气管软化的病因,以便安全地进行治疗,尤其是对于巨大甲状腺肿患者。
