二腔チューブ挿管後に閉塞性線維性偽膜気管炎を来し声門下狭窄に至った1症例

A Case of Subglottic Stenosis due to Obstructive Fibrinous Pseudomembrane Tracheitis after Double-lumen Endotracheal Tube Intubation

要旨

　73歳，女性，胸腔鏡下右下葉切除術が予定された。32Fr左用二腔チューブが挿入困難のため28Frで分離肺換気を行った。術後5日目に気管支鏡で声門下狭窄を認め，気管切開を行った。声門下から摘出した組織は線維性組織が主体で，挿管時の気管損傷が原因で閉塞性線維性偽膜気管炎に至ったと考えられた。

　A 73-year-old woman presented for video-assisted right lower lobectomy. Because the insertion of a 32-Fr left double-lumen endotracheal tube was difficult, airway management was performed with a 28-Fr double-lumen endotracheal tube. On postoperative Day 5, tracheostomy was performed to manage airway stenosis immediately below the vocal cord. The removed tissue was mainly fibrotic tissue, identified as obstructive fibrinous pseudomembrane tracheitis due to intubation-related tracheal injury.
