A Case of Postoperative Subglottic Stenosis despite Discontinuation of Double-Lumen Tube Insertion

Key Points

• The aim is to explore a case of postoperative subglottic stenosis despite the discontinuation of a double-lumen tube.
• Described a clinical case of a 76-year-old female patient.
• Performed right lower lobe resection using a bronchial blocker due to resistance during intubation.
• Monitored respiratory status post-surgery.
• Diagnosed subglottic stenosis on the fourth postoperative day and performed tracheostomy.
• Despite initial normal respiratory status, symptoms of airway obstruction developed the day after surgery.
• Subglottic stenosis was diagnosed four days postoperatively.
• Cuff pressure was managed appropriately during the procedure, yet mucosal damage was suspected as the cause of stenosis.
