A 71-yr-old female with a malignant thyroid tumour was to undergo thyroidectomy under general anaesthesia. Preoperative chest x-ray and plain computed tomography (CT) showed severe tracheal stenosis. Three-dimensional figures of the trachea and a virtual bronchoscopic movie were obtained from multi-slice CT to evaluate the stenotic region and to simulate fibroscopic tracheal intubation, respectively. After induction of general anaesthesia with propofol, a tracheal tube was successfully passed through the stenotic region under the guide of a fibroscope as simulated in the virtual movie. We conclude that multi-slice CT is useful for preoperative airway evaluation for patients with stenosis and distortion of the trachea.
一名71岁患有甲状腺恶性肿瘤的女性拟在全身麻醉下接受甲状腺切除术。术前胸部X线和普通计算机断层扫描（CT）显示严重气管狭窄。从多层CT获得气管的三维图像和虚拟支气管镜电影，分别用于评估狭窄区域和模拟纤维支气管镜气管插管。在使用丙泊酚诱导全身麻醉后，在虚拟电影中模拟的纤维镜引导下，气管导管成功通过狭窄区域。我们得出结论，多层CT对气管狭窄和变形患者的术前气道评估有用。
