摘要

胸腔科醫師偶而會遇到氣管狹窄的問題，原因包括感染，創傷，氣管插管後併發症，先天性以及外圍組織壓迫所造成。相對而言，最常發生氣管狹窄的原因仍然是氣管插管及氣切管插管所造成。在此，我們陳述一位82歲因為前三個月接受過氣管插管而造成氣管狹窄的女性病人，傳統胸部X光並無法顯示狹窄的位置及範圍；雖然軟式支氣管鏡檢查發現在聲帶3公分以下，氣管明顯狹窄但卻無法再深入檢查。在這種情況下，利用胸部電腦斷層及2-D，3-D重組影像來估計氣管狹窄的大小。影響的範圍及週邊的組織，有助於進一步的診斷。經一系列評估完後，病人接受雷射及安置永久性支架治療，病情迅速改善，現在持續穩定門診追蹤中。

Tracheal stenosis is occasionally encountered by chest physicians. We report a patient with tracheal stenosis which developed after endotracheal intubation three months previous. Routine chest roentgenography was not able to show the stenosis (apparently) and bronchoscopy could not pass through the narrowed lumen to yield a careful assessment. Nevertheless, computerized tomography with 2-dimensional and 3-dimensional reconstruction easily demonstrated the tracheal stenosis, with an assessment of the entire anatomy and surrounding tissue, as well as of the severity and length of the stenosis. After laser therapy and permanent stent implantation, the patient was discharged in stable condition, and was followed-up at the outpatient department.
